station where it can be heard today. In the early 1960s, the Federal Communications Commission adopted a standard for transmitting and receiving stereo signals on a single channel of the FM band. In addition to delivering stereo sound, FM broadcasting provided clearer sound quality and better resistance to interference than AM, thus being ideal for broadcasting the beautiful music format. In Baltimore, Maryland, programmer Art Wander developed a beautiful music format for the 50,000-watt NBC affiliate WBAL/1090. The station format launched in the fall of 1960 featured music sweeps of lush instrumentals with subtle comments from their staff announcers. The format changed to sports and talk when competing FM stations broadcast beautiful music and easy listening. In 1963, Marlin Taylor created a custom-designed beautiful music format at Philadelphia's WDVR. Within four months, WDVR became the #1 rated FM station in the Philadelphia market. This was one of the first big successes in FM broadcasting, and was instrumental in establishing the viability of FM. WDVR was a resource for mature listeners who were driven from AM radio at the time when WFIL and WIBG (and others) switched to rock 'n' roll programming. WDVR's billboards made the adult audience aware of the new station. Airtime resell practice. Libraries of music for radio stations Others, such as Jim Schulke, devised a method of buying air time on FM stations in bulk and reselling the blocks to interested advertisers. Schulke formed Stereo Radio Productions (SRP) to help his stations get better ratings and pull in more agency advertising dollars. His stations used six hundred reels of stereo reel-to-reel tape set on multiple machines so that 15 minute segments would play at a time, alternating from one player to another, allowing a varied programming format in which no half-hour was repeated within a two-week period. One of Schulke's stations using this "matched flow" concept was WDVR's chief competitor in the beautiful music format in Philadelphia, WWSH-FM. Peters Productions in San Diego, California was active throughout the late 1960s through the early 1980s. At one time Peters Productions offered 7 different syndicated radio formats plus radio/television "station image" packages (custom jingle and integrated promotional graphics packages.) The most popular syndicated radio format was a beautiful music format on a library of 100 reel-to-reel tapes, with 6 new reels provided per month. It originated when founder Ed Peters was station manager of San Diego radio station KFMB-FM.
