Dallas programmer gets national role.

Infinity continues to step up its commitment to the Jack format. On June 3, it flipped longtime oldies signals WCBS New York and WJMK Chicago.

Today it named Kurt Johnson VP of programming for its Jack stations, which play a mix of classic hits, mainly from the '70s and '80s. Johnson, who is VP programming, Infinity/Dallas, programs the company's first Jack station, KJKK Dallas, as well as smooth jazz KOAI.

"As program director of our first Jack station, Kurt has been instrumental in the format's adoption at several Infinity stations across the country," Infinity Broadcasting president of programming Rob Barnett said in a statement. "He has successfully guided KJKK to a position of leadership in the market where it now ranks among the most listened stations in Dallas. Kurt's first-hand experience will be invaluable to Infinity as we continue to evolve our eight Jack stations."
