Pioneers in the talk-show landscape Phil Donahue and Dr. Oz are the final subjects of TV Guide Network's Hollywood Icons and Innovators series.
Donahue, whose eponymous talk show ran from 1970 to 1996, holds the record for the longest continuously running syndicated talk show. He received nine Emmy awards in his broadcasting career. Oz, whose television career began as an expert on The Oprah Winfrey Show, has led the charge — sometimes controversially — in health infotainment.
In the conclusion of the network's four-part series, Dr. Oz sits down with Donahue as the two share memorable interviews, mistakes and moments.
Hollywood Icons and Innovators airs Sunday at 9/8c on TV Guide Network.
