Super Bowl Sunday is the most important event in the US sporting calendar and it's also the launch day for the biggest TV ads of the year. With ads costing millions of dollars to place, it's only the big boys that can afford it, which explains why so many of them come from tech giants from around the world.

One of the most popular ads from this year's game was the Volkswagen commercial, featuring a mini Darth Vader, but the NFL-loving public was also treated to glimpses of the Motorola Xoom and The Daily tablet newspaper. Other highlights included a Best Buy ad featuring dark prince of rock Ozzy Osbourne and teenaged pop phenomenon Justin Bieber making some well-placed gags about 4G and a ad featuring half-time entertainers, the Black Eyed Peas. Other tech advertisers included Verizon,, and Sony.

With so much emphasis on the ads, you might have forgotten about the game itself. If you don't want to know the result, then don't read the the next sentence - consider this your "spoiler alert".

The Green Bay Packers won 31-25 against the Pittsburgh Steelers, making it their fourth Super Bowl win and their first title since 1996. If you care more about the ads than the football, then read on to see all the tech ads from Super Bowl Sunday rounded up in one place.
