The tug-of-war between US media firm Viacom and cable TV provider Time Warner over iPad TV streaming is unlikely to come to an end in the near future as the two parties took the issue to court.

Viacom are opposing Time Warner’s move to distribute TV contents to the iPad, claiming Viacom has no right to distribute TV contents over unconventional media such as iPad.

Google has won the copyright case as a judge ruled out the 1 billion dollars lawsuit brought by the Viacom accusing Google for allowing its video sharing site YouTube to use copyright materials without prior permission.

Viacom has accused Google of a massive intentional copyright infringement. But the judge in Manhattan erased all the claims saying Google and YouTube could not be held liable for those videos posted illegally.

The court ruling in the 2007-filed copyright infringement lawsuit by media giant Viacom against Internet search biggie Google's video-sharing site YouTube recently went in favor of Google, with US District Judge Louis Stanton dismissing the case on the grounds that Google had acted expeditiously after being apprised by Viacom of copyrighted works on YouTube site.

A Wednesday decision by US District Judge Louis L. Stanton granted Google the request for summary judgment - thereby siding with Google's YouTube in the $1-billion copyright infringement lawsuit that Viacom filed against the online video-sharing site in 2007.

The Google-Viacom legal scuffle has been part of the ongoing debate pertaining to the terms under which content can be distributed over the Internet, and who is responsible for policing piracy.

In a friends-of-the-court brief filed on behalf of Google’s YouTube on Wednesday in the US District Court for the Southern District of New York, four prominent Web services – including Yahoo, Facebook, eBay, and IAC/InterActiveCorp – urged a federal judge to dismiss the copyright infringement lawsuit filed by Viacom in 2007.

It has been reported that on Thursday, Viacom released further documents in its lawful conflict with YouTube. This was condemning Google of making a planned attempt to profit from copyright violation and force copyright owners into licensing agreements.

Viacom was charged by Youtube, for pulling a media stunt instead of presenting anything novel.
