The media behemoth Viacom has engaged in numerous battles with YouTube over copyright infringement over the years. But two years ago, Viacom ended up in the embarrassing position of mistakenly bringing to light the fact that it had committed some copyright infringement of its own. When Viacom demanded that YouTube remove a clip of a North Carolina politician's campaign commercial from a VH1 program called Web Junk 2.0, it emerged that VH1 hadn't obtained permission to use the clip in the first place.
