The relationship between Paley and his news staff was not always smooth. His friendship with Edward R. Murrow, one of the leading lights in the CBS news division (and by then a vice president of CBS), suffered during the 1950s over the hard-hitting tone of the Murrow-hosted "See It Now" series. The implication was that the network's sponsors were uneasy about some of the controversial topics of the series, leading Paley to worry about lost revenue to the network as well as unwelcome scrutiny during the era of McCarthyism. In 1955, Alcoa withdrew its sponsorship of "See It Now", and eventually the program's weekly broadcast on Tuesdays was stopped, though it continued as a series of special segments until 1958.
