"We Bring a Program"; the call sign and their associated meaning were suggested by Herbert Hoover during his tenure as chairman of what was then the Federal Radio Commission prior to the radio station's sign-on in 1922; in reality, they were sequentially assigned with no meaning. Among the local programs that aired on Channel 5 in its early years included the Saturday night country music/dance program Barn Dance, music series Bobby Peters Jamboree and the children's programs See-Saw Zoo and Kitty's Playhouse. When Channel 5 signed on, it was apparent that Dallas and Fort Worth were going to be collapsed into a single television market due to the close proximity of the two cities; despite the fact that Dallas and Tarrant counties bordered one another, Arbitron had initially designated their respective county seats as separate markets (the counties that surrounded Tarrant County on the western half of the Metroplex were part of the Fort Worth market, while those surrounding Dallas County in the eastern half of the metropolitan region were part of the Dallas market). However, Carter, who had long been a booster for the Fort Worth area, did not care whether Dallas residents could view Channel 5's broadcast signal, which provided rimshot coverage within most of central and eastern Dallas County, including Dallas proper.
