Viacom’s piracy dispute with YouTube and its parent company Google is at the forefront of the rapidly-changing copyright law landscape

At the beginning of July, a US court ordered Google to disclose the personal details and viewing habits of every user to have visited the immensely popular video-sharing website YouTube. This amounted to a huge 12 terabytes of data. The reason? Viacom, which owns MTV and Paramount Pictures – the studio behind films ranging from White Christmas to Jackass: The Movie – is suing YouTube’s owner, Google, for massive copyright infringement. It is alleging that 160,000 unauthorised clips had been viewed more than 1.5 billion times on the video-sharing portal.
