A few notes on Associated Press history

  This O'Reilly post notes several nice bits of the history of the AP, a useful topic for anyone interested in media or information history. 

First comes the 1850s creation of the enterprise, including some practical collaboration to share news. 

Next is a brief note on the teletype.  I appreciate the section on teletypespeak:

"--30--" meant "end of story" or "end of transmission." It's a convention that many writers continue to use today. "--73--" meant "thanks" and "--88--" stood for "love and kisses." Add telex jargon to the odd history of abbreviated communication that today includes emoticons and SMS acronyms.
