Shut down:  Oct. 27, 2010

LimeWire had been downloaded more than 200 millions times and acted as a conduit to hundreds of millions of free downloads. The gratis program felt the wrath of the U.S. federal court system and the RIAA, becoming the recipient of an injunction stating creator Mark Gordon committed “copyright infringement, engaged in unfair competition, and induced others to commit copyright infringement," forcing the P2P service to shut down. The RIAA didn’t stop there, as the trade group announced it would sue LimeWire for up to $75 trillion in damages. In retaliation, the international hacker collective, Anonymous, executed a denial-of-service attack that took down the RIAA’s website.
