While bloggers and others online pushed back at the CBS story with a lot of clever work, much of the "information" flying around the Net about the documents was inaccurate -- including claims that the font didn't exist in 1972 (Times Roman was first used in 1931; the IBM version was known as Press Roman in the 70s), that proportional spacing wasn't available on typewriters (IBM introduced it in 1941) and that the superscript "th" wasn't possible then (superscript capability could be purchased as an option).Some of these mistakes where in the early postings by Powerline, and it wasn't until I'd heard an expert on Hewitt's radio show and I'd seen this at LGF's that I said "put a fork in it" and started posting on the faked documents here at PrestoPundit. My first posting was this one, linked that day by The Corner. Posted by Greg Ransom
