The Radio America-syndicated program “The Dr. Bob Martin Show” is celebrating 28 years in national syndication. Radio America recently expanded the program to three hours, and it now airs live on Sundays from 9:00 am to 12:00 noon ET on more than 150 stations. Dr. Martin got his start in radio as a fill-in talk host on KFYI, Phoenix and for two decades he served as a full time iHeartMedia staffer. Radio America VP for affiliate marketing Steve Graham says, “We are excited to celebrate Dr. Bob’s anniversary in this highly competitive industry. The additional hour to Dr. Bob’s show will only enhance his presence. He has been a solid part of our lineup for decades. It’s exciting to continue and deepen our partnership with his program.”
