A graduate of Lafayette High School (1976) and Brooklyn College (1982), Malzberg worked at 77 WABC for over twenty-five years in several capacities, as an overnight political talk show host, a sports commentator, and co-host of a regular afternoon show with Richard Bey called The Buzz. He hosted the New York Jets pre, post and half time shows in the mid 80's, the New York Yankees pre and post games shows in 1990 and the New Jersey Devils pre and post game shows in 1996 and 1997. In 2004, Malzberg joined the staff of New York City radio station WWRL-1600 AM, where he co-hosted an early morning show with "New York Daily News" columnist Karen Hunter. In July 2005, the short-lived morning team of Hunter and Malzberg was disbanded as Malzberg left WWRL.
