The MDA Labor Day Telethon was an annual telethon held on Labor Day in the United States to raise money for the Muscular Dystrophy Association (MDA). The Muscular Dystrophy Association was founded in 1950 with hopes of gaining the American public's interest. The show was hosted by comedian, actor, singer and filmmaker Jerry Lewis from its 1966 inception until 2010. The history of MDA's telethon dates back to the 1950s, when the Jerry Lewis Thanksgiving Party for MDA raised funds for the organization's New York City area operations. The telethon was held annually on Labor Day weekend beginning in 1966, and raised $2.45 billion for MDA from its inception through 2009.
