As early as 1947, singing station identifications (ID’s) were used by KLIF in Dallas, Texas. One of the musicians working on KLIF at the time was a Dallas native by the name of Bill Meeks. In addition to leading two bands that performed live on the station, Bill also sold commercial time to the shows’ sponsors. He participated in creating commercials and jingles for those sponsors, as well as making musical identifications for the station itself. They got favourable reaction, and KLIF did well. After a while, some of Bill’s clients urged him to devote more time to working on their advertising needs. So in 1951 Mr. Meeks formed his own advertising agency.

He named it PAMS, which is an acronym for Production Advertising Merchandising Service. PAMS designed a group of ten jingles, and called the package simply "Series 1". A more elaborate "Series 2" followed shortly thereafter. The idea was that stations would hear a demonstration tape of the jingles (a "demo"), and re-write the lyrics to suit their own requirements. PAMS would then assemble the vocal group in a studio and re-sing the jingles using the new lyrics, over the already-existing instrumental backgrounds. This is the essence of jingle syndication. It began at PAMS in the early 1950"s, and the process continues to this day.

For a period spanning three decades, PAMS, based in Dallas, was the most influential and imitated source of radio jingles in the world, and an integral part of the sound of legendary stations.
