P2P File Sharing Sharing music with Napster became so popular a few years back that record companies were angry, considered it stealing and sued the creator of the software. Courts ruled it illegal and shut it down. Well, shortly afterwards a few other peer-to-peer networks have popped up such as Kaaza, which has been ruled legal in the U.S. and not only is music shared with these new P2P networks, but other files such as videos, software, and documents are also shared. Millions of internet users are using P2P networks daily. learn more about Kaaza ruling
