Tim Berners Lee – behind you!
Amazon has been selling stuff online since as far back as 1973, at least if you believe this:
In fact, Google lists over 51,000 pages with this date on Amazon. And mind you – it is the exact date September 4 1973, not a day less, nor a day more.
Of course, some geeks may claim this has to do with some Amazon programmers’ default value, but the POSIX time for this date is just a boring 115945200, not some fun number like 1234567890. I prefer to attribute this to some evil Bezosish conspiracy theory, now I just need to figure out what it was.
Suggestions?
The Alter Egozi 
Birthday of Stacy Sanches, playmate of the year 1996.
So that was it. All I could find was just birthdate of Carmit Bachar (an Israeli Pussycat Doll? WTF??)
Actually, the first male full frontal nudity in Playboy — Johnny Crawford, September 1973 issue (source).
Actually, The Likud party was founded at the same day, which explains everything.

Uri, what a treasure trove! even with these tiny sized front pages (can’t believe they want to charge for this) the main title is still readable, good history lessons…
