The one and only. :-)
Mary Hart is a legend among American television presenters. She co-hosted the syndicated entertainment news magazine show "Entertainment Tonight" from 1982 to 2011. The former local news anchorwoman, who in the seventies had worked at KMTV-TV in Omaha (anchoring the news alongside Chuck Roberts, later of CNN's Headline News channel) and KFOR-TV in Oklahoma City, briefly co-hosted a show with the ubiquitous Regis Philbin in 1981. After it was quickly canceled, "Entertainment Tonight," having been on the air for only a few months itself, interviewed Ms. Hart and asked her what the news of the cancellation felt like. Someone at "Entertainment Tonight" must have liked her charisma; she was hired by the show as a correspondent almost immediately and became its co-host shortly thereafter.
Five male "Entertainment Tonight" co-hosts - including the insufferable John Tesh - came and went between 1982 and 2011, but Mary Hart remained a constant presence. Her journalism background seemed apropos, as she became as seemingly permanent a fixture as the news anchors of yore by delivering the latest news on movies, music and related topics (i.e., the celebrities making the movies and music) every weeknight for nearly thirty years.
In 2011, Mary Hart stepped down from "Entertainment Tonight," deciding it was time to move on. She was and remains a class act in a medium (television) not particularly known for its class.
Fun fact: She's married to Burt Sugarman, the TV producer best known for his seventies NBC series "The Midnight Special."
