Viacom sued Google last year for 1$ billion, on the count that its video sharing service YouTube features a series of copyright infringements. Google responded that the lawsuit threatens the basic way millions of people communicate and exchange information.

According to Viacom, Google should get more involved in finding ways to stop users from uploading copyrighted materials, seeing that at this point YouTube’s only measure for this problem enables owners to complain about a certain post and block it from being viewed. So far, Viacom has records of more than 150,000 unauthorized clips uploaded on the popular web site, among which several shows from MTV, Comedy Central and also other network broadcasts like "The Daily Show with Jon Stewart" and "South Park."

"The availability on the YouTube site of a vast library of the copyrighted works of plaintiffs and others is the cornerstone of defendants' business plan," Viacom said, according to the Associated Press.

Google expressed its concern that such a lawsuit could be considered a direct threat to freedom on the internet. Also, its officials wanted to make it clear that YouTube’s policy regarding the copyright issue goes far beyond its legal obligations and that the company provides a significant aid for owners protecting their work.

Google’s lawyers are very confident about the defense they managed to build and are ready to take it all the way to the Supreme Court.
