Among other tasks, the Graphics Arts Department was required to generate graphics, including title graphics, for the Republican and Democratic National Conventions. In order to comprehend the magnitude of the task they faced, it is helpful to understand how television graphics were created in those times. </p><p> Graphics, including all title graphics (i.e. "President Lyndon B. Johnson” or  "Walter Cronkite”) were set in type or drawn by graphic artists. The graphic was photographed using 35-mm film, the film developed, and a 35-mm slide generated. The time to generate a slide exceeded one hour. The slide, when used, was placed in a special projector, scanned by a television camera, and keyed into the studio video feed. This method was known as ‘Superimposition’.</p><div class="thumb tleft"><div class="thumbinner" style="width:302px;"><a href="/File:Vidifont_Figure_1-Superimposition.jpg" class="image"><img alt="" src="/w/images/thumb/a/ad/Vidifont_Figure_1-Superimposition.jpg/300px-Vidifont_Figure_1-Superimposition.jpg" decoding="async" width="300" height="184" class="thumbimage" srcset="/w/images/thumb/a/ad/Vidifont_Figure_1-Superimposition.jpg/450px-Vidifont_Figure_1-Superimposition.jpg 1.5x, /w/images/thumb/a/ad/Vidifont_Figure_1-Superimposition.jpg/600px-Vidifont_Figure_1-Superimposition.jpg 2x" /></a> <div class="thumbcaption"><div class="magnify"><a href="/File:Vidifont_Figure_1-Superimposition.jpg" class="internal" title="Enlarge"></a></div>Figure 1 - Superimposition</div></div></div><p>Since the news department had to be prepared to identify any speaker who might appear before the cameras during the convention, Bass was faced with creating in excess of 4000 slides in advance for each convention. If an individual who was not a delegate or an alternate was called upon to give a seconding speech or to participate in an interview, a title slide probably would not be available. Bass was seeking an instantaneous, graphics-quality titling capability solution to the problem. The goal was to produce graphics that could be transparently mixed with artwork created using traditional methods. </p><p><br /> Bass requested that CBS's Television Engineering Department find a solution to his titling challenge. The Engineering Department investigated <a href="/Generators" title="Generators">electronic generators</a> then available. These devices offered characters based on matrix structures, and none of them approached the quality of the typeset graphics, meeting the criteria set by Bass. My name is Stanley Baron. In 1966, I was an engineer employed at CBS Laboratories, the research arm of CBS, Inc. One of my assignments was to assist Walter Cronkite's staff at CBS News in New York on the application of digital technology to program production. Bass discussed his problem with me, and I also suggested the use of an electronic graphics generator. </p><p>In the discussion that followed, Bass related the findings of the CBS Television Engineering Department, and I related previous work in which I had been involved starting in 1962 on digital display processors for military and other government agency information display applications. This prior work included television compatible character and icon generators (albeit not of graphics quality) and non-real-time, more costly, graphics quality systems for film applications that provided choices of font typefaces and graphics. In 1965, I had worked on a system developed by the staff of CBS Laboratories on behalf of Linotron that provided for digital scanning and storage of typefaces and graphics and was designed for writing on film. As such, the system did not operate in real-time and would not support the 30 second-per-frame refresh rate required for television applications. However, the resolution requirements were more than a magnitude greater than that required for broadcast television applications. This system provided for storage and retrieval of multiple fonts. </p><p>I told Bass that if he was to identify a typeface, I could fabricate an electronic generator that would create characters and icons (such as the CBS 'Eye' or any other logo) in the desired type face and size for keying into the video transmission from the studio. Bass explained that he was looking for a proportional-width generator, one in which the letters ‘W' or ‘M' would be wider than the letter ‘I’, and he had been advised that all of the companies contacted by CBS Television Engineering had told CBS that they did not know how to electronically generate proportional characters. </p><p>I proposed a simple way to generate proportional characters, which was to store a separate timing code for each character or icon to vary the length of time between the start of the character or icon and the time the next character or icon was addressed (initiated) in memory. This solution was later documented in the Vidifont patents.<sup id="cite_ref-refnum1_1-0" class="reference"><a href="#cite_note-refnum1-1">[1]</a></sup> </p><p>When I returned to CBS Laboratories that afternoon, I described my proposed solution to the Laboratories' management, including: my immediate supervisor, Hank Oppenheimer; his boss, Ken Moore; and the Laboratories' Vice President of Engineering, Ren McMann.

The feasibility prototype was well received, and many of the visitors inquired about acquiring such a device. CBS management in New York was not convinced, however, that a market existed for such a device, and a request for funding development of a production model was rejected.Visual Electronics, a company involved in marketing systems to broadcasters, had introduced a matrix-based character generator system for television titling based on the A.B. Dick 990 DCU (Display Control Unit)<sup id="cite_ref-refnum3_3-0" class="reference"><a href="#cite_note-refnum3-3">[3]</a></sup> at the 1967 NAB (National Association of Broadcasters conference). Representatives of Visual Electronics showed interest in the Vidifont system during demonstrations they attended at CBS Laboratories. In response to Visual Electronics' request, in October 1968, I drafted a specification<sup id="cite_ref-refnum4_4-0" class="reference"><a href="#cite_note-refnum4-4">[4]</a></sup> for a graphics generator based on the feasibility prototype, and the two companies entered into a partnership to build and market the product. </p><h2><span class="mw-headline" id="Prior_art_in_character_generators">Prior art in character generators</span></h2> <p>A review of the existing prior art helps to understand the improvement provided by the Vidifont. Existing electronic generators, such as display processors I had worked on at GE in 1962, the A. B.

They decided that being able to supply equipment that performed the titling function at 50% of the capital cost of existing equipment (the camera used to scan the slides) and, further, reduced the daily expenditure for film should find acceptance with station management. The partners were not concerned about developing support from the graphic artists, as Bass’ reaction to the prototype convinced them the system would be enthusiastically received by that community. The plan was to prove that a market existed through sales of the Vidifont Mark-I, the basic version of the product, and then fund development of the envisioned total capability from the sales income. </p><p> Although the original concept provided for scanning type-faces and storing the fonts in random-access-memory (RAM), which would allow artists to change fonts by downloading software, the per-bit cost of memory devices at that time would have significantly increased the price of the unit, exceeding the cost goals. Therefore, a system was designed using wired-core read-only-memories to provide the strokes that formed the alphanumeric characters and icons. (Semiconductor read-only-memories, later known as “ROMs”, were not commercially available at this time.)</p><div class="thumb tleft"><div class="thumbinner" style="width:302px;"><a href="/File:Vidifont_Figure_5-Vidifont_Wired-Core_Memory.jpg" class="image"><img alt="" src="/w/images/thumb/7/70/Vidifont_Figure_5-Vidifont_Wired-Core_Memory.jpg/300px-Vidifont_Figure_5-Vidifont_Wired-Core_Memory.jpg" decoding="async" width="300" height="168" class="thumbimage" srcset="/w/images/thumb/7/70/Vidifont_Figure_5-Vidifont_Wired-Core_Memory.jpg/450px-Vidifont_Figure_5-Vidifont_Wired-Core_Memory.jpg 1.5x, /w/images/thumb/7/70/Vidifont_Figure_5-Vidifont_Wired-Core_Memory.jpg/600px-Vidifont_Figure_5-Vidifont_Wired-Core_Memory.jpg 2x" /></a> <div class="thumbcaption"><div class="magnify"><a href="/File:Vidifont_Figure_5-Vidifont_Wired-Core_Memory.jpg" class="internal" title="Enlarge"></a></div>Figure 5 - Vidifont wired-core memory</div></div></div><p>To further keep costs within the desired bounds, the system specification limited the set of capabilities. The device would store two different sets of fonts, would colorize each word differently, and provided a capability to put the display in motion to generate both ‘rolls’ (credits at the end of a program) and ‘crawls’ (the warning messages that appear at the bottom of the screen). Each font set consisted of upper and lower case letters of the alphabet plus numbers, punctuation marks, and one or more icons such as station logos, all proportionally spaced. </p><p><br /> The Vidifont project team consisting of seven engineers and technicians that included myself and Harvey Caplan, Bill Harrick, Stephen Kreinik, Scott Pursell, Altaf Rahman, and Ollie St. Jean designed, built, and tested a system meeting the agreed upon specification in under a year.  As with any new technological innovation, the project went through the usual phases of design and construction of an engineering prototype followed by fabrication of pre-production prototype units prior to beginning full production runs. The engineering prototype was constructed and tested in 1969. A small pre-production run representing the final design was built for demonstration at the March 1970 NAB Conference held in Chicago and for shipment to early customers. Visual Electronics asked me to suggest a name for the product. The name I had been using for the feasibility prototype was “Vidifont”, an abbreviation of ‘video font generator,’ and that was adopted as the name of the device. </p><p>Second-generation units produced in the third year of sales, took advantage of lowered costs of computer memory. This version of the Vidifont more closely conformed to the original concept, in that characters were of higher resolution and could be scanned by a camera system and then stored either on disc or directly in random-access-memory allowing for a larger repertoire of type-faces. Colorization went from word-by-word to character-by-character and later, provided for different colors on a pixel-by-pixel basis within the same character or icon. </p><p>The week prior to shipping the first units to the 1970 NAB Conference, having just completed researching the ability to copyright the name “Vidifont,” the CBS legal department noted the absence of a patent disclosure. In the crunch to produce the system, no one involved had generated a patent disclosure. </p><p>Fortunately, all parties involved in the demonstrations starting in 1966 had been required to sign a non-disclosure agreement, and since the specification dated 16 October 1968, fully described the system, it served as the basis of a patent disclosure signed that week.<sup id="cite_ref-refnum6_6-0" class="reference"><a href="#cite_note-refnum6-6">[6]</a></sup> </p> <h2><span class="mw-headline" id="Public_reaction_to_the_Vidifont">Public reaction to the Vidifont</span></h2> <div class="thumb tleft"><div class="thumbinner" style="width:302px;"><a href="/File:Vidifont_Figure_6a-_Vidifont_Mark-I.jpg" class="image"><img alt="" src="/w/images/thumb/f/fc/Vidifont_Figure_6a-_Vidifont_Mark-I.jpg/300px-Vidifont_Figure_6a-_Vidifont_Mark-I.jpg" decoding="async" width="300" height="342" class="thumbimage" srcset="/w/images/thumb/f/fc/Vidifont_Figure_6a-_Vidifont_Mark-I.jpg/450px-Vidifont_Figure_6a-_Vidifont_Mark-I.jpg 1.5x, /w/images/thumb/f/fc/Vidifont_Figure_6a-_Vidifont_Mark-I.jpg/600px-Vidifont_Figure_6a-_Vidifont_Mark-I.jpg 2x" /></a> <div class="thumbcaption"><div class="magnify"><a href="/File:Vidifont_Figure_6a-_Vidifont_Mark-I.jpg" class="internal" title="Enlarge"></a></div>Figure 6 - Vidifont Mark-I</div></div></div><p>When the Vidifont Mark-I was shown at the 1970 NAB Conference in Chicago, it attracted a significant amount of interest. After the first morning, the reaction to the Vidifont by the attendees at the Conference could be compared to the crowds awaiting the opening of the doors to a shopping mall on the day after Thanksgiving, and there was a constant stream of traffic to see this new innovation.  The very positive comments of the attendees and the sales volume booked at the show obliterated any questions as to whether the effort had been warranted. The demonstration units were delivered to customers soon after the NAB Conference. Additional production units became available later in 1970. The Vidifont quickly established a market for electronic graphics generators. </p><p><br /> In 1969, a message storage device had been integrated into the Vidifont system to facilitate composing and editing of displays off-line prior to going ‘on-air.’ Systems Research Corporation (SRC) a company located on Long Island was the supplier. The staff at CBS Labs shared their vision of future generator developments with SRC, since many of these developments, such as RAM storage of fonts, would require further developments in peripheral storage device capability and capacity. The same storage device was incorporated by Visual Electronics for use with the A.B. Dick character generator. SRC noted the success of the A. B. Dick generators, and two years later, they entered the market with a competing character generator, which they called "Chiron."  By the end of 1970, SRC also noted the success of the Vidifont and, three years later, they entered the market with a competing graphics generator, which they called ‘Chyron II.’ For the first few years, all electronic graphics generators were called by the generic name ‘Vidifont.’ </p><p>A few years after the Vidifont came to the market, CBS, Inc. changed the Laboratories business model, the rights to the products produced by the Laboratories were sold to other companies, and eventually, the Laboratories ceased operations. Over the next few years, Chyron came to dominate the market for electronic graphics generators. </p><p>The Vidifont has been recognized by others as the first digital graphics generator. In 1986, the British IEE held a celebration of the 50th anniversary of the first British television broadcasts from Alexandria Palace in 1936. The celebration was capped by a three-day “International Conference on the History of Television” held in London on 13-15 November 1986. Invitations to participate were restricted to individuals who had made original contributions to the advancement of the television sciences, and I was invited to speak as the inventor of the first digital graphics device. An indication of how revolutionary the Vidifont was perceived to be at the time was reflected at the presentation of a paper at “The National Seminar on Illustration and Design for Television.” The seminar program was designed to serve the graphics artist community. I was invited to speak for 20 minutes, to be followed by a 10 minute Q&A period. When my time was done, the audience protested, and the moderator decided to accede to the audience’s demands. At the one-hour mark, I invited two colleagues from CBS Laboratories, Harvey Caplan and Tom Hindle, to join me on the stage, and at the two-hour mark the three of us were seated on the edge of the stage with jackets off, passing the microphone between us involved in an exciting dialogue with the audience. The Vidifont presentation was scheduled to begin at 09:00 a.m., and finally ended when the session broke for lunch just passed noon. </p><p>In 1992, the National Academy of Television Arts and Sciences recognized the Vidifont with an EMMY award to CBS. </p> <h2><span class="mw-headline" id="Beyond_the_Vidifont_Mark-I">Beyond the Vidifont Mark-I</span></h2> <p>A reviewer might be left with the impression that the development of the Vidifont electronic graphics generator ended with the level of performance described for the Vidifont Mark-I. The following additional information should help to understand the pace of development of the technology. </p><p>The original Vidifont Mark-I device was limited in pixel resolution to slightly below 50 ns by cost considerations. As digital component costs and speed characteristics improved, successive generations of Vidifont units provided improved pixel resolution.<sup id="cite_ref-refnum7_7-0" class="reference"><a href="#cite_note-refnum7-7">[7]</a></sup> </p> <div class="thumb tleft"><div class="thumbinner" style="width:302px;"><a href="/File:Vidifont_Figure_7-Vidivote_Display.jpg" class="image"><img alt="" src="/w/images/thumb/3/33/Vidifont_Figure_7-Vidivote_Display.jpg/300px-Vidifont_Figure_7-Vidivote_Display.jpg" decoding="async" width="300" height="203" class="thumbimage" srcset="/w/images/thumb/3/33/Vidifont_Figure_7-Vidivote_Display.jpg/450px-Vidifont_Figure_7-Vidivote_Display.jpg 1.5x, /w/images/thumb/3/33/Vidifont_Figure_7-Vidivote_Display.jpg/600px-Vidifont_Figure_7-Vidivote_Display.jpg 2x" /></a> <div class="thumbcaption"><div class="magnify"><a href="/File:Vidifont_Figure_7-Vidivote_Display.jpg" class="internal" title="Enlarge"></a></div>Figure 7 - Vidivote display</div></div></div><p>Early on, “Vidivote” was offered as a standard package that supported more sophisticated displays including the ability to generate display templates used in sporting events, elections, etc. with automatic entry of statistical results.

I further argued that while analog television allowed us to capture and present the world we lived in to the viewing audience, the use of digital technology would ultimately allow us to create and portray worlds that existed only in our imaginations. </p><p>One lesson learned from the Vidifont Mark-I project was the importance of setting realistic goals. While I was, in part, uplifted when I received permission to launch the design of the Vidifont Mark-I, I couldn’t help also feel somewhat disappointed. I had a vision for a grand machine that would revolutionize the way graphics were generated in television production. A machine that could reproduce electronically, animated sequences that would appear so close to natural as to be indistinguishable from real life. The Mark-I was constrained to a far simpler capability. The Mark-I was a step in the right direction, but I wanted to take more than a step, I was eager to run the whole race. </p><p>As it turned out, the Vidifont Mark-I, while limited in capability, created a revolution, and the income from the sales of the machine financed all the following steps that took decades to achieve. Given the state of the art in digital hardware and software technology in 1968, it still would have taken decades to achieve the original vision at a price the customers could afford had we chosen the path I preferred. Had we taken that path, the sponsors would have lost interest somewhere along the way, and we would never have reached our goal. My map to the future was the wrong map to follow. </p><p>The lesson learned? Sometimes it is better to focus on the race, one step at a time. In my future projects, while keeping my eye on the finish line, I learned to savor each of the steps that brought me there. </p> <h2><span class="mw-headline" id="End_Notes:">End Notes:</span></h2> <div class="mw-references-wrap"><ol class="references"> <li id="cite_note-refnum1-1"><span class="mw-cite-backlink"><a href="#cite_ref-refnum1_1-0">↑</a></span> <span class="reference-text">Baron, S.N.; "A Television Compatible Character Generator", Information Display Publications, 1972.</span> </li> <li id="cite_note-refnum2-2"><span class="mw-cite-backlink"><a href="#cite_ref-refnum2_2-0">↑</a></span> <span class="reference-text">Bass, Rudi; “The development of CBS News 36”, The Journal of Typographic Research, 1:No.4, October 1967.</span> </li> <li id="cite_note-refnum3-3"><span class="mw-cite-backlink"><a href="#cite_ref-refnum3_3-0">↑</a></span> <span class="reference-text">“History of Electronic Character Generating Systems in TV Broadcasting and CATV”, Visual Electronics Laboratories, April 1974, p.1.</span> </li> <li id="cite_note-refnum4-4"><span class="mw-cite-backlink"><a href="#cite_ref-refnum4_4-0">↑</a></span> <span class="reference-text">CLD (CBS Laboratories Division) Document #68-230U; “A TV Compatible Display Titler: Vidifont”, 18 October 1968.</span> </li> <li id="cite_note-refnum5-5"><span class="mw-cite-backlink"><a href="#cite_ref-refnum5_5-0">↑</a></span> <span class="reference-text">Moore, J.
