April Fools Day seems to be the day where the tech companies shine brightest.

Every April 1, Google and a host of other tech companies play pranks on the innocent minds of the consumer. There was the year every video on YouTube was a Rick Roll (the online term for when a video gets cut off by Never Going To Give You Up by Rick Astley). There was Google's Gmail Autopilot prank from two years ago, when the company announced a new feature that would analyze an email and format an automat response to that email.

This year was no different. Google was up to its usual antics. YouTube was as well, and a few others have gotten in on the fun. Here's a list of April Fools Day tech jokes.
