This colorful logo debuted in the 1966-67 Season and was used until December 31, 1975. It is interesting to observe that the CBS eye is no longer a part of the graphic; this was the result of an eviction from CBS to separate the non-O&O CBS station's news from being confused with the CBS network news operations. This 'unbranding' lasted for many years until competition from cable and satellite made CBS and the other networks urge affiliates to reincorporate the network ID into local promotion and news.
1976 was America's Bicentennial. In honor of the year, 'Big 13' becomes the 'Original 13.' The logo consisted of a white circle with a blue 13 in it, surrounded by 13 red stars. Coincidentally, WTVT's former analog channel position coincide with the 13 stars.
1989–1997 (1989-1994 CBS 13 & 1994-Present as FOX 13 Tampa Bay, FL.)
On December 12, 1994, WTVT switched affiliations from CBS to Fox following a deal with New World Communications and the Fox Broadcasting Company to affiliate all New World stations with Fox, sending CBS programming to WTSP. The above logo was used as an alternate logo from that time until it was retired. Fox Television Stations became the owner and operator in 1997, when New World was sold to News Corporation.
This logo branding, currently in use by most of the Fox O&Os, is based on the Fox News logo; with their website names ("myfox(city name).com") based off of the domain for the social network Myspace, which former Fox parent News Corporation briefly owned. WTVT was the first Fox O&O station to use a logo in this style. From December 2005 until February 2006, this logo was only used on the station's 11PM newscast, Fox 13 NewsEdge. They were also branded as Fox 13 on screen along with other Fox-owned stations, such as KSAZ (Fox 10).
