It did offer the ability to tag messages with keywords, which the user could use in searches. The system acted primarily in the form of a buy and sell system with the tags taking the place of the more traditional <a href="/wiki/Classified_advertising" title="Classified advertising">classifications</a>. But users found ways to express themselves outside these bounds, and the system spontaneously created stories, poetry and other forms of communications. The system was expensive to operate, and when their host machine became unavailable and a new one could not be found, the system closed in January 1975. </p><p>Similar functionality was available to most <a href="/wiki/Mainframe_computer" title="Mainframe computer">mainframe</a> users, which might be considered a sort of ultra-local BBS when used in this fashion.

The user would pick up the phone, dial a number, then press the handset into rubber cups on the top of the modem. Disconnecting at the end of a call required the user to pick up the handset and return it to the phone. Examples of direct-connecting modems did exist, and these often allowed the host computer to send it commands to answer or hang up calls, but these were very expensive devices used by large banks and similar companies. </p><p>With the introduction of <a href="/wiki/Microcomputer" title="Microcomputer">microcomputers</a> with expansion slots, like the <a href="/wiki/S-100_bus" title="S-100 bus">S-100 bus</a> machines and <a href="/wiki/Apple_II" title="Apple II">Apple II</a>, it became possible for the modem to communicate instructions and data on separate lines. These machines typically only supported asynchronous communications, and <a href="/wiki/Synchronous_serial_communication" title="Synchronous serial communication">synchronous</a> modems were much more expensive than asynchronous modems. A number of modems of this sort were available by the late 1970s. This made the BBS possible for the first time, as it allowed software on the computer to pick up an incoming call, communicate with the user, and then hang up the call when the user logged off. </p><p>The first public <a href="/wiki/Dial-up" class="mw-redirect" title="Dial-up">dial-up</a> BBS was developed by <a href="/wiki/Ward_Christensen" title="Ward Christensen">Ward Christensen</a> and <a href="/wiki/Randy_Suess" title="Randy Suess">Randy Suess</a>, members of the Chicago Area Computer Hobbyists' Exchange (CACHE). According to an early interview, when Chicago was snowed under during the <a href="/wiki/Great_Blizzard_of_1978" title="Great Blizzard of 1978">Great Blizzard of 1978</a>, the two began preliminary work on the <a href="/wiki/Computerized_Bulletin_Board_System" class="mw-redirect" title="Computerized Bulletin Board System">Computerized Bulletin Board System</a>, or <a href="/wiki/CBBS" title="CBBS">CBBS</a>.<sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup> The system came into existence largely through a fortuitous combination of Christensen having a spare S-100 bus computer and an early Hayes internal modem, and Suess's insistence that the machine be placed at his house in <a href="/wiki/Chicago" title="Chicago">Chicago</a> where it would be a local phone call for more users. Christensen patterned the system after the <a href="/wiki/Cork_board" class="mw-redirect" title="Cork board">cork board</a> his local computer club used to post information like "need a ride".

Internal modems like the ones used by CBBS and similar early systems were usable, but generally expensive due to the manufacturer having to make a different modem for every computer platform they wanted to target. They were also limited to those computers with internal expansion, and could not be used with other useful platforms like <a href="/wiki/Video_terminal" class="mw-redirect" title="Video terminal">video terminals</a>. External modems were available for these platforms but required the phone to be dialed using a conventional handset.<sup id="cite_ref-10" class="reference"><a href="#cite_note-10"><span class="cite-bracket">[</span>a<span class="cite-bracket">]</span></a></sup> Internal modems could be software-controlled to perform outbound and inbound calls, but external modems had only the data pins to communicate with the host system. </p><p>Hayes' solution to the problem was to use a small <a href="/wiki/Microcontroller" title="Microcontroller">microcontroller</a> to implement a system that examined the data flowing into the modem from the host computer, watching for certain command strings. This allowed commands to be sent to and from the modem using the same data pins as all the rest of the data, meaning it would work on any system that could support even the most basic modems. The Smartmodem could pick up the phone, dial numbers, and hang up again, all without any operator intervention. The Smartmodem was not necessary for BBS use but made overall operation dramatically simpler. It also improved usability for the caller, as most terminal software allowed different phone numbers to be stored and dialed on command, allowing the user to easily connect to a series of systems. </p><p>The introduction of the Smartmodem led to the first real wave of BBS systems. Limited in speed and storage capacity, these systems were normally dedicated solely to messaging, private email and public forums. File transfers were extremely slow at these speeds, and file libraries were typically limited to text files containing lists of other BBS systems. These systems attracted a particular type of user who used the BBS as a unique type of communications medium, and when these local systems were crowded from the market in the 1990s, their loss was lamented for many years.<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources.

While this gave the market a bad reputation, it also led to its greatest success. During the early 1990s, there were a number of mid-sized software companies dedicated to BBS software, and the number of BBSes in service reached its peak. </p><p>Towards the early 1990s, BBS became so popular that it spawned three monthly magazines, <i><a href="/wiki/Boardwatch" title="Boardwatch">Boardwatch</a></i>, <i>BBS Magazine</i>, and in Asia and Australia, <i>Chips 'n Bits Magazine</i> which devoted extensive coverage of the software and technology innovations and people behind them, and listings to US and worldwide BBSes.<sup id="cite_ref-ChipsnBits_12-0" class="reference"><a href="#cite_note-ChipsnBits-12"><span class="cite-bracket">[</span>11<span class="cite-bracket">]</span></a></sup> In addition, in the US, a major monthly magazine, <i><a href="/wiki/Computer_Shopper_(US_magazine)" title="Computer Shopper (US magazine)">Computer Shopper</a></i>, carried a list of BBSes along with a brief abstract of each of their offerings. </p> <div class="mw-heading mw-heading3"><h3 id="GUIs">GUIs</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Bulletin_board_system&action=edit&section=6" title="Edit section: GUIs"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:More_ANSI_art.png" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/f/f8/More_ANSI_art.png/220px-More_ANSI_art.png" decoding="async" width="220" height="128" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/f/f8/More_ANSI_art.png/330px-More_ANSI_art.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/f/f8/More_ANSI_art.png/440px-More_ANSI_art.png 2x" data-file-width="632" data-file-height="368" /></a><figcaption>ANSI art BBS logo</figcaption></figure> <p>Through the late 1980s and early 1990s, there was considerable experimentation with ways to develop user-friendly interfaces for BBSes. Almost every popular system used ANSI-based color menus to make reading easier on capable hardware and terminal emulators, and most also allowed cursor commands to offer command-line recall and similar features. Another common feature was the use of <a href="/wiki/Autocomplete" title="Autocomplete">autocomplete</a> to make menu navigation simpler, a feature that would not re-appear on the Web until decades later. </p><p>A number of systems also made forays into GUI-based interfaces, either using character graphics sent from the host, or using custom GUI-based terminal systems. The latter initially appeared on the <a href="/wiki/Macintosh" class="mw-redirect" title="Macintosh">Macintosh</a> platform, where <a href="/wiki/TeleFinder" title="TeleFinder">TeleFinder</a> and <a href="/wiki/FirstClass" title="FirstClass">FirstClass</a> became very popular. FirstClass offered a host of features that would be difficult or impossible under a terminal-based solution, including bi-directional information flow and non-blocking operation that allowed the user to exchange files in both directions while continuing to use the message system and chat, all in separate windows. Will Price's "Hermes", released in 1988, combined a familiar PC style with Macintosh GUI interface.<sup id="cite_ref-13" class="reference"><a href="#cite_note-13"><span class="cite-bracket">[</span>12<span class="cite-bracket">]</span></a></sup> (Hermes was already "venerable" by 1994 although the Hermes II release remained popular.<sup id="cite_ref-14" class="reference"><a href="#cite_note-14"><span class="cite-bracket">[</span>13<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-15" class="reference"><a href="#cite_note-15"><span class="cite-bracket">[</span>14<span class="cite-bracket">]</span></a></sup>) <a href="/wiki/Skypix" title="Skypix">Skypix</a> featured on Amiga a complete <a href="/wiki/Markup_language" title="Markup language">markup language</a>. It used a standardized set of icons to indicate mouse driven commands available online and to recognize different filetypes present on BBS storage media. It was capable of transmitting data like images, audio files, and audio clips between users linked to the same BBS or off-line if the BBS was in the circuit of the FidoNet organization. </p><p>On the PC, efforts were more oriented to extensions of the original terminal concept, with the GUI being described in the information on the host. One example was the <a href="/wiki/Remote_Imaging_Protocol" title="Remote Imaging Protocol">Remote Imaging Protocol</a>, essentially a picture description system, which remained relatively obscure. Probably the ultimate development of this style of operation was the dynamic page implementation of the <a href="/wiki/University_of_Southern_California" title="University of Southern California">University of Southern California</a> BBS (USCBBS) by Susan Biddlecomb, which predated the implementation of the <a href="/wiki/HTML" title="HTML">HTML</a> <a href="/wiki/Dynamic_web_page" title="Dynamic web page">Dynamic web page</a>.

Another delay followed due to a long <a href="/wiki/ITU-T_V.34" class="mw-redirect" title="ITU-T V.34">V.34</a> standards process before 28.8 kbit/s was released, only to be quickly replaced by 33.6 kbit/s, and then 56 kbit/s. </p><p>These increasing speeds had the side effect of dramatically reducing the noticeable effects of channel efficiency.

Technically, Internet service offered an enormous advantage over BBS systems, as a single connection to the user's <a href="/wiki/Internet_service_provider" title="Internet service provider">Internet service provider</a> allowed them to contact services around the world. In comparison, BBS systems relied on a direct point-to-point connection, so even dialing multiple local systems required multiple phone calls. Internet protocols also allowed a single connection to be used to contact multiple services simultaneously; for example, downloading files from an <a href="/wiki/FTP" class="mw-redirect" title="FTP">FTP</a> library while checking the weather on a local news website.

The ubiquitous <a href="/wiki/Commodore_64" title="Commodore 64">Commodore 64</a> (introduced in 1982) was a common platform in the 1980s.

In the late 1980s, a handful of BBS developers implemented multitasking communications routines inside their software, allowing multiple phone lines and users to connect to the same BBS computer. These included Galacticomm's <a href="/wiki/MajorBBS" class="mw-redirect" title="MajorBBS">MajorBBS</a> (later WorldGroup), eSoft <a href="/wiki/The_Bread_Board_System" title="The Bread Board System">The Bread Board System</a> (TBBS), and <a href="/wiki/Falken_(bulletin_board_system)" title="Falken (bulletin board system)">Falken</a>.

However, some home computer manufacturers extended the ASCII character set to take advantage of the advanced color and graphics capabilities of their systems. BBS software authors included these extended character sets in their software, and terminal program authors included the ability to display them when a compatible system was called. Atari's native character set was known as <a href="/wiki/ATASCII" title="ATASCII">ATASCII</a>, while most Commodore BBSes supported <a href="/wiki/PETSCII" title="PETSCII">PETSCII</a>.

Unless a caller was using terminal emulation software written for, and running on, the same type of system as the BBS, the session would simply fall back to simple ASCII output. For example, a <a href="/wiki/Commodore_64" title="Commodore 64">Commodore 64</a> user calling an Atari BBS would use ASCII rather than the native character set of either. As time progressed, most terminal programs began using the <a href="/wiki/ASCII" title="ASCII">ASCII</a> standard, but could use their native character set if it was available. </p><p>COCONET, a BBS system made by Coconut Computing, Inc., was released in 1988 and only supported a GUI (no text interface was initially available but eventually became available around 1990), and worked in EGA/VGA graphics mode, which made it stand out from text-based BBS systems.

Bulletin Board Systems could be found for almost every hobby and interest. Popular interests included politics, religion, music, <a href="/wiki/Matchmaker.com" title="Matchmaker.com">dating</a>, and <a href="/wiki/Alternative_lifestyle" title="Alternative lifestyle">alternative lifestyles</a>. Many system operators also adopted a <a href="/wiki/Theme_(computing)" title="Theme (computing)">theme</a> in which they customized their entire BBS (welcome screens, prompts, menus, and so on) to reflect that theme. Common themes were based on <a href="/wiki/Fantasy" title="Fantasy">fantasy</a>, or were intended to give the user the illusion of being somewhere else, such as in a <a href="/wiki/Sanatorium" title="Sanatorium">sanatorium</a>, wizard's castle, or on a <a href="/wiki/Pirate_ship" class="mw-redirect" title="Pirate ship">pirate ship</a>. </p><p>In the early days, the file download library consisted of files that the system operators obtained themselves from other BBSes and friends. Many BBSes inspected every file uploaded to their public file download library to ensure that the material did not violate copyright law. As time went on, <a href="/wiki/Shareware" title="Shareware">shareware</a> CD-ROMs were sold with up to thousands of files on each <a href="/wiki/CD-ROM" title="CD-ROM">CD-ROM</a>. Small BBSes copied each file individually to their hard drive. Some systems used a CD-ROM drive to make the files available. Advanced BBSes used Multiple CD-ROM disc changer units that switched 6 CD-ROM disks on demand for the caller(s). Large systems used all 26 DOS drive letters with multi-disk changers housing tens of thousands of copyright-free shareware or freeware files available to all callers. These BBSes were generally more family-friendly, avoiding the seedier side of BBSes. Access to these systems varied from single to multiple modem lines with some requiring little or no confirmed registration. </p><p>Some BBSes, called elite, <a href="/wiki/Warez" title="Warez">WaReZ</a>, or pirate boards, were exclusively used for distributing <a href="/wiki/Copyright_infringement_of_software" class="mw-redirect" title="Copyright infringement of software">cracked software</a>, <a href="/wiki/Phreaking" title="Phreaking">phreaking</a> materials, and other questionable or unlawful content. These BBSes often had multiple modems and phone lines, allowing several users to upload and download files at once. Most elite BBSes used some form of new user verification, where new users would have to apply for membership and attempt to prove that they were not a law enforcement officer or a <i><a href="/wiki/Lamer" title="Lamer">lamer</a>.</i> The largest elite boards accepted users by invitation only. Elite boards also spawned their own subculture and gave rise to the <a href="/wiki/Slang" title="Slang">slang</a> known today as <a href="/wiki/Leet" title="Leet">leetspeak</a>. </p><p>Another common type of board was the <i>support BBS</i> run by a manufacturer of computer products or software. These boards were dedicated to supporting users of the company's products with question and answer forums, news and updates, and downloads. Most of them were not a free call. Today, these services have moved to the Web. </p><p>Some general-purpose Bulletin Board Systems had special levels of access that were given to those who paid extra money, uploaded useful files or knew the system operator personally. These specialty and pay BBSes usually had something unique to offer their users, such as large file libraries, <a href="/wiki/Warez" title="Warez">warez</a>, <a href="/wiki/Pornography" title="Pornography">pornography</a>, <a href="/wiki/Chat_room" title="Chat room">chat rooms</a> or <a href="/wiki/Internet" title="Internet">Internet</a> access. </p><p>Pay BBSes such as The <a href="/wiki/WELL_(virtual_community)" class="mw-redirect" title="WELL (virtual community)">WELL</a> and Echo NYC (now Internet forums rather than dial-up), <a href="/wiki/ExecPC_BBS" title="ExecPC BBS">ExecPC</a>, PsudNetwork and <a href="/wiki/MindVox" title="MindVox">MindVox</a> (which folded in 1996) were admired for their close, friendly communities and quality discussion forums. However, many free BBSes also maintained close communities, and some even had annual or bi-annual events where users would travel great distances to meet face-to-face with their on-line friends. These events were especially popular with BBSes that offered <a href="/wiki/Chat_room" title="Chat room">chat rooms</a>. </p><p>Some of the BBSes that provided access to illegal content faced opposition. On July 12, 1985, in conjunction with a <a href="/wiki/Credit_card_fraud" title="Credit card fraud">credit card fraud</a> investigation, the <a href="/wiki/Middlesex_County,_New_Jersey" title="Middlesex County, New Jersey">Middlesex County, New Jersey</a> Sheriff's department raided and seized The Private Sector BBS, which was the official BBS for <a href="/wiki/Grey_hat" title="Grey hat">grey hat</a> hacker quarterly <a href="/wiki/2600_Magazine" class="mw-redirect" title="2600 Magazine">2600 Magazine</a> at the time.<sup id="cite_ref-Psector_21-0" class="reference"><a href="#cite_note-Psector-21"><span class="cite-bracket">[</span>18<span class="cite-bracket">]</span></a></sup> The notorious <a href="/wiki/Rusty_n_Edie%27s_BBS" title="Rusty n Edie's BBS">Rusty n Edie's BBS</a>, in <a href="/wiki/Boardman,_Ohio" class="mw-redirect" title="Boardman, Ohio">Boardman, Ohio</a>, was raided by the FBI in January 1993 for trading unlicensed software, and later sued by <a href="/wiki/Playboy" title="Playboy">Playboy</a> for copyright infringement in November 1997.

Information contained on that BBS never left the system, and users would only interact with the information and user community on that BBS alone. However, as BBSes became more widespread, there evolved a desire to connect systems together to share messages and files with distant systems and users. The largest such network was <a href="/wiki/FidoNet" title="FidoNet">FidoNet</a>. </p><p>As is it was prohibitively expensive for the hobbyist system operator to have a dedicated connection to another system, FidoNet was developed as a <a href="/wiki/Store_and_forward" title="Store and forward">store and forward</a> network. Private email (Netmail), public message boards (Echomail) and eventually even file attachments on a FidoNet-capable BBS would be bundled into one or more archive files over a set time interval. These archive files were then compressed with <a href="/wiki/ARC_(file_format)" title="ARC (file format)">ARC</a> or <a href="/wiki/ZIP_(file_format)" title="ZIP (file format)">ZIP</a> and forwarded to (or polled by) another nearby node or hub via a dialup <a href="/wiki/Xmodem" class="mw-redirect" title="Xmodem">Xmodem</a> session. Messages would be relayed around various FidoNet hubs until they were eventually delivered to their destination. The hierarchy of FidoNet BBS nodes, hubs, and zones was maintained in a routing table called a Nodelist. Some larger BBSes or regional FidoNet hubs would make several transfers per day, some even to multiple nodes or hubs, and as such, transfers usually occurred at night or in the early morning when toll rates were lowest. In Fido's heyday, sending a Netmail message to a user on a distant FidoNet node, or participating in an Echomail discussion could take days, especially if any FidoNet nodes or hubs in the message's route only made one transfer call per day. </p><p>FidoNet was platform-independent and would work with any BBS that was written to use it. BBSes that did not have integrated FidoNet capability could usually add it using an external FidoNet <a href="/wiki/Front_end_processor_(program)" class="mw-redirect" title="Front end processor (program)">front-end</a> mailer such as SEAdog, <a href="/wiki/FrontDoor" title="FrontDoor">FrontDoor</a>, BinkleyTerm, InterMail or D'Bridge, and a mail processor such as <a href="/wiki/FastEcho" title="FastEcho">FastEcho</a> or <a href="/wiki/Squish_(FidoNet)" class="mw-redirect" title="Squish (FidoNet)">Squish</a>. The front-end mailer would conduct the periodic FidoNet transfers, while the mail processor would usually run just before and just after the mailer ran. This program would scan for and pack up new outgoing messages, and then unpack, sort and "toss" the incoming messages into a BBS user's local email box or into the BBS's local message bases reserved for Echomail. As such, these mail processors were commonly called "scanner/tosser/packers". </p><p>Many other BBS networks followed the example of FidoNet, using the same standards and the same software. These were called FidoNet Technology Networks (FTNs). They were usually smaller and targeted at selected audiences. Some networks used <a href="/wiki/QWK_(file_format)" title="QWK (file format)">QWK</a> doors, and others such as <a href="/wiki/RelayNet" title="RelayNet">RelayNet</a> (RIME) and <a href="/wiki/WWIVnet" title="WWIVnet">WWIVnet</a> used non-Fido software and standards. </p><p>Before commercial Internet access became common, these <a href="/wiki/Computer_network" title="Computer network">networks</a> of BBSes provided regional and international <a href="/wiki/E-mail" class="mw-redirect" title="E-mail">e-mail</a> and message bases. Some even provided <a href="/wiki/Gateway_(computer_networking)" class="mw-redirect" title="Gateway (computer networking)">gateways</a>, such as UFGATE, by which members could send and receive e-mail to and from the <a href="/wiki/Internet" title="Internet">Internet</a> via <a href="/wiki/UUCP" title="UUCP">UUCP</a>, and many FidoNet discussion groups were shared via gateway to <a href="/wiki/Usenet" title="Usenet">Usenet</a>. Elaborate schemes allowed users to download binary files, search <a href="/wiki/Gopher_(protocol)" title="Gopher (protocol)">gopherspace</a>, and interact with distant <a href="/wiki/Computer_program" title="Computer program">programs</a>, all using plain-text e-mail. </p><p>As the volume of FidoNet Mail increased and newsgroups from the early days of the Internet became available, satellite data downstream services became viable for larger systems. The satellite service provided access to FidoNet and Usenet newsgroups in large volumes at a reasonable fee. By connecting a small dish and receiver, a constant downstream of thousands of FidoNet and Usenet newsgroups could be received. The local BBS only needed to upload new outgoing messages via the modem network back to the satellite service. This method drastically reduced phone data transfers while dramatically increasing the number of message forums. </p><p>FidoNet is still in use today, though in a much smaller form, and many Echomail groups are still shared with Usenet via FidoNet to Usenet gateways. Widespread abuse of Usenet with <a href="/wiki/Spam_(electronic)" class="mw-redirect" title="Spam (electronic)">spam</a> and <a href="/wiki/Pornography" title="Pornography">pornography</a> has led to many of these FidoNet gateways to cease operation completely. </p> <div class="mw-heading mw-heading2"><h2 id="Shareware_and_freeware">Shareware and freeware</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Bulletin_board_system&action=edit&section=13" title="Edit section: Shareware and freeware"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1236090951"><div role="note" class="hatnote navigation-not-searchable">Main article: <a href="/wiki/Shareware" title="Shareware">Shareware</a></div> <p>Much of the <a href="/wiki/Shareware" title="Shareware">shareware</a> movement was started via user distribution of software through BBSes.

The Internet has largely erased the distinction of shareware – most users now download the software directly from the developer's website rather than receiving it from another BBS user "sharing" it. Today, shareware often refers to electronically distributed software from a small developer. </p><p>Many commercial BBS software companies that continue to support their old BBS software products switched to the shareware model or made it entirely free. Some companies were able to make the move to the Internet and provide commercial products with BBS capabilities. </p> <div class="mw-heading mw-heading2"><h2 id="Features">Features</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Bulletin_board_system&action=edit&section=14" title="Edit section: Features"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>A classic BBS had: </p> <ul><li>A <a href="/wiki/Computer" title="Computer">computer</a></li> <li>One or more <a href="/wiki/Modem" title="Modem">modems</a></li> <li>One or more phone lines, with more allowing for increased concurrent users</li> <li>A <a href="/wiki/List_of_BBS_software" title="List of BBS software">BBS software package</a></li> <li>A <a href="/wiki/Sysop" title="Sysop">sysop</a> – system operator</li> <li>A user community</li></ul> <p>The BBS software usually provides:<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources.
