In 1967, the "Chronicle" sold KTRK to Capital Cities Broadcasting (later to become Capital Cities Communications), earning a handsome return on its 1937 purchase of KTRH. Under Capital Cities ownership, KTRK introduced its "Circle 13" logo – which is loosely patterned after the Circle 7 logo long used by ABC stations and affiliates broadcasting on channel 7 – in 1971. The original version, used until 1995, was set in a Helvetica typeface, with the bottom of the "3" trailing off outside the circle (similar also to the way the stem of the number 7 terminates at the bottom of the Circle 7 logo)--a nod to livestock branding of the Old West.
