Google, Facebook and YouTube fool users on April 1

Tech Crunch also announced that Google was entering the nuclear arms industry after it bought a nuclear plant.

In the good tradition of April Fools’ Day hoaxes, YouTube announced that it will make all videos look like 1911, with sepia images.

Google had other pranks as well for April Fools’ Day. On the morning of April 1, the company published a job advertisement for an “autocompleter.”

“Every day people start typing more than a billion searches on Google and expect Google to predict what they are looking for. In order to do this at scale, we need your help. As a Google Autocompleter, you’ll be expected to successfully guess a user’s intention as he or she starts typing instantly. In a fraction of a second, you’ll need to type in your prediction that will be added to the list of suggestions given by Google. Don’t worry, after a few million predictions you’ll grow the required reflexes,” Google announced.

Also, American websites announced a partnership between Google and Virgin who was to be called Project Virgile. Sergey Brin, Larry Page and Richard Branson said they intended to lead a group of people in colonizing the planet Mars.

On the other hand, the company Groupon announced that it owned the 1st of April. Given the uncertainties regarding copyright, Groupon decided to acquire the rights to Fools’ Day.

In April Fools’ Day tradition, Facebook and Zynga announced that they will ally to launch a dating site based on online games to help Internet users to quickly and easily find a partner.
