WinMX (Windows Music Exchange) is a freewarepeer-to-peer file sharing program authored in 2000 by Kevin Hearn (president of Frontcode Technologies) in Windsor, Ontario (Canada). According to one study, it was the number one source for online music in 2005 with an estimated 2.1 million users. Frontcode Technologies itself abandoned development of WinMX in September 2005, but developers brought the service back online within a few days by releasing patches. WinMX continues to be used by a community of enthusiasts.
