9. FCC 'may fine' then-Yahoo CEO Carol Bartz over swearing
Yahoo's former chief executive Carol Bartz was famed above many thing for swearing following a mini tirade at former TechCrunch editor Michael Arrington. To get in on the joke and turn what could've been a bit of a tricky public relations problem into something funny for April Fools' Day in 2010, the Web giant published a piece on claims the Federal Communication Commission's (FCC) was "looking into" her swearing after she allegedly swore incessantly on television. But, as with many of these jokes, it never actually happened.
10. Amazon puts cloud computing servers in the real cloud
Amazon may be a bit fusty in the enterprise space with little but business to go on, but its cloud-based platform division thought it would liven things up for 2009's April Fools' Day by announcing it would take its cloud computing platform to the actual clouds. The plan would be to deliver servers running EC2 instances connected via WiMAX (the alternative to LTE) and lasers to communicate with ground. Alas, it was pure rubbish but Amazon still pulled a good one.
Bonus: Conficker a bust, fails to do anything
There's a bonus: the Conficker worm. The kicker here is that it was actually real and set to 'blow up' on April 1, 2009. But nothing actually happened. The worm spread through machines across the world and was set to activate and receive instructions, in what was thought to be one of the largest botnets of the time, but command servers never sent the instructions. While most weren't laughing, it turned out to be on the most part a busted flush.
