Almost one year before Viacom filed its high-profile, yet so-far unsuccessful lawsuit agianst YouTube, journalist Robert Tur brought a nearly identical copyright infringement case against the video-sharing site. Tur, like Viacom, The Football Association Premier League and other content owners, lost the case in May. Viacom is appealing, but Tur this week agreed that he would not. Tur also promised to pay $20,000 to YouTube. Why did Tur do so? The court papers don't say, but observers speculate that Tur must have agreed to the terms because he leaked confidential documents to Cnet last year.
