from 2002 through 2003, a number of bittorrent services were established, including suprnova.org, isohunt, torrentspy, and the pirate bay. in september 2003, the riaa began filing lawsuits against users of p2p file sharing networks such as kazaa. as a result of such lawsuits, many universities added file sharing regulations in their school administrative codes (though some students managed to circumvent them during after school hours). also in 2003, the mpaa started to take action against bittorrent sites, leading to the shutdown of torrentse and sharelive in july 2003. with the shutdown of edonkey in 2005, emule became the dominant client of the edonkey network. in 2006, police raids took down the razorback2 edonkey server and temporarily took down the pirate bay.
