If Activision really wants to reach the widest possible audience with DJ Hero, TV commercials are probably the best way to expedite that process. If said TV commercials happen to feature Daft Punk's wonderfully catchy "Around the World," even better.After the break, see one TV ad starring a digital version of Daft Punk (though, since the band is ostensibly robotic, what's the difference?) and another featuring both a clip of Justice vs. Public Enemy, and an improbably shiny DJ Hero controller. And if you like those, Activision continues to upload preview clips of in-game songs to its YouTube channel.
