Layoffs at CBS Radio: CBS Radio Networks has fired 14% of its staff in response to the weak advertising market, a spokeswoman said. Helene Blieberg said the decision eliminated 22 jobs in programming, sales, marketing and research; neither news staff nor on-air personnel were affected. Blieberg said advertising sales have been down 20% each month this year. In addition, CBS Radio pays a high price for the rights to broadcast major sports events, further squeezing the network, she said.
