Grennan worked for WLS radio from 1959-1960, and then WNBQ/WMAQ the NBC owned and operated station in Chicago.
Grennan was probably best known to the Chicago television audience as the host of It's Academic, a weekly quiz show of the late 1960s where three teams of students from Chicago area high schools competed to answer questions on academic subjects and general knowledge.
