Some sources are needed for it(news reports, historical studies, etc.). It's good writing, and interesting, but it needs to be sourced. </p><p>The paragraph: "Its origin dates back to 1988, when an engineer at Bell research lab deviced a way to carry digital signal over the unused frequency spectrum. This allows ordinary phone line to provide digital communication without blocking access to voice services. Bells management however were not enthusiastic about it as it was not as profitable as renting out a second line for those consumers who prefered to still have acess to the phone when dialing out. This however changed in the late 90s when cable companies started marketing broadband internet access. Realising that most consumers would prefer broadband over a second dial out line, Bell companies rushed out the DSL technology that they had been sitting on for the past decade as an attempt to slow broadband internet access uptake." - <a class="external text" href="https://en.wikipedia.org/w/index.php?title=Digital_Subscriber_Line&diff=7167807&oldid=7167121">diff</a> (Also posted on <a href="/wiki/User_talk:Wk_muriithi" title="User talk:Wk muriithi">User talk:Wk muriithi</a>) <a href="/wiki/User:JesseW" title="User:JesseW">JesseW</a> 19:48, 6 Apr 2005 (UTC) </p> <dl><dd>wk muriithi replied on my talk page saying he got it from "Crafting and Executing strategy 14th edition by Arthur A.
