In the wake of a panic swap of WTOP-TV (now WUSA) to the (Detroit) Evening News Association for its WWJ-TV (now WDIV) in 1978, followed by the sale of both radio stations later in the year, the "Post" decided to spin off their broadcasting interests into a company of its own. The Post-Newsweek name itself would later spread to the "Post"-owned cable operations (now known as Cable One and a company identical in structure to Post-Newsweek Stations). During the 1970s and 1980s, the stations tended to have vaguely similar on-air looks, along with the common slogan "The One & Only Channel/TV (number)"; some of the stations continue to use this or a variant as a slogan.
