In 1969, WPIX first introduced the original version of the current "Circle 11" logo, the "11" in the logo closely resembled the World Trade Center, which was not completed until four years later.
Beginning in September 1976 and continuing until 1986, WPIX branded itself as "11 Alive"; the "Alive" branding was made popular by Atlanta's WXIA-TV (as well as other stations owned by WXIA's parent company Gannett), who also started using the "11 Alive" branding the same month as WPIX and continues to use it to this day. The "Circle 11" logo was dropped during this period.
During the station's broadcast of the 1994 New York City Marathon, WPIX retired the "Circle 11" logo once again and introduced a new logo that would be used during the station's run as an affiliate of The WB. Though this logo was phased out from regular on-air usage by 1996, the station continued to use this logo in the intro for its 10 p.m. newscast until 1998.
In January 1995, WPIX became a charter affiliate of The WB Television Network, becoming one of the DE-facto flagship stations of the network through parent Tribune Company's minority stake in the network. The logo introduced in 1994 was then modified to include The WB's logo to reflect the change.
Logo used in late 90s' for Kids' WB-sourced and syndicated kids programming.
In 2006, The WB and UPN announced that they would merge their programming into a new network called The CW; WPIX became a charter affiliate of The CW in September of that year.
In October 2008, WPIX temporarily re-branded as "WPIX 11" and reintroduced the "Circle 11" logo for the third time after a fourteen-year hiatus (using a modified version featuring the 1994-2006 "11" logo) as part of a company-wide re-branding that saw most of Tribune's CW affiliates de-emphasize The CW name and logo from their branding.
