Mr. Podhoretz talked about his life and his writings and answered telephoned questions from viewers. He talked about politics, literary criticism and many other topics. In the 1950s he was a founder of the political left, but later moved to the political right. That transformation served as the subject for some of his books, including Ex-Friends, Breaking Ranks, and his latest, My Love Affair With America. He has written for and edited Commentary magazine for forty years.
