The entertainment industry has obsessed over the threat of peer-to-peer file sharing since the introduction of Napster in 1999. The sharing of television content may present a compelling case for fair use under the long-standing "Betamax" decision. Some argue that television sharing is fundamentally different than the distribution of music or movies since television is often distributed for free over public airwaves. However, a determination of fair use is unlikely because of the fundamental differences between recording a program and downloading it, recent regulation to suppress unauthorized content distribution and shifts in the television market brought on by new technology.
