Logos
KTRK's "Circle 13" logo is loosely patterned after the Circle 7 logo long used by ABC stations and affiliates. It is similar to that of former sister station WTVG in Toledo, Ohio, only that KTRK calls itself ABC 13 while WTVG is known as 13 ABC (also WTVG's version of the logo does not include a design of the Texas state flag).
Its previous logo, which ran from 1971 until 1995, was a crooked "Circle 13." It recalled livestock branding of the Old West and was set in Helvetica font, with the bottom of the "3" trailing off out of the circle (similar also to the way the stem of the number 7 terminates at the bottom of the Circle 7 logo). In 1986 because of the Capital Cities/ABC Merger, the trailing portion was "trimmed" as the logo was turned slightly horizontal in a similar fashion to today's version. Since July 3, 1992, both logos have been superimposed over a stylized version of the Texas state flag.
