copyright 2009, The Washington Post WASHINGTON -- A Washington Post obituary of Walter Cronkite incorrectly described WTOP-TV, which eventually became WUSA, as being a CBS affiliate when Cronkite worked with the station in the 1950s. It was operated by CBS and jointly owned by The Washington Post Co. and CBS. The obituary also incorrectly said that NBC's nightly news program, hosted by Chet Huntley and David Brinkley, was two weeks behind 'The CBS Evening News' in expanding to a half-hour broadcast in 1963. NBC expanded its program one week after CBS did.
