Stephen Hill founded the new-age radio show "Hearts of Space" in 1973. In 1983, was picked up by NPR for syndication to 230 affiliates nationally, and year later was started a record label Hearts of Space Records. On Valentine's Day in 1987, the former Los Angeles rock radio station KMET changed to a full-time new-age music format with new call letters KTWV, branded as "The Wave". During The Wave's new-age period, management told the station employees to refer to The Wave as a "mood service" rather than a "radio station". DJs stopped announcing the titles of the songs, and instead, to maintain an uninterrupted mood, listeners could call a 1–800 phone number to find out what song was playing. News breaks were also re-branded and referred to as "wave breaks". Other new-age-specialty radio programs included Forest's "Musical Starstreams" and John Diliberto's "Echoes". Most major cable television networks have channels that play music without visuals, including channels for New age, such as the "Soundscapes" channel on Music Choice. The two satellite radio companies Sirius Satellite Radio & XM Satellite Radio each had their own channels that played new-age music. Sirius—Spa (Sirius XM) (73), XM—Audio Visions (77). When the two merged in November 2008 and became SiriusXM, the Spa name was retained for the music channel with the majority of Audio Vision’s music library being used.
