Input: Question: When was the organization that launched WEVD founded? Passage:WEVD (originally broadcasting at 1220 kHz AM, later on 1300 kHz, for many years on 1330 kHz and finally on 1050 kHz), was an American brokered programming radio station with some news-talk launched in August 1927 by the Socialist Party of America. Making use of the initials of recently deceased party leader Eugene Victor Debs in its call sign, the station operated from Woodhaven in the New York City borough of Queens. The station was purchased with a $250,000 radio fund raised by the Socialist Party in its largest fundraising effort of the 1920s and was intended as spreading progressive ideas to a mass audience. A number of national trade unions and other institutions aided the Socialists in obtaining the station.
