WJZ-TV

1948–1956
WJZ-TV originally signed on as WAAM on November 1, 1948, a primary ABC affiliate at the time.

1963–1999
The logo design, especially the font (called "Westinghouse" or "Anklepants" (due to a similar typeface) by some people), was originally introduced when then-owner Group W introduced its design language in 1963.

In 1995, CBS entered into an agreement with the Westinghouse Broadcasting Company, which owned WJZ-TV and four other stations. This resulted in WJZ-TV switching from ABC to CBS, sending that ABC affiliation to WMAR-TV channel 2, who lost its NBC affiliation back to WBAL-TV channel 11. As of 2020, WJZ-TV and KPIX-TV are the only two former Group W stations to still use the Group W typeface in their station logos.

1999–present
Long after the switch to CBS, WJZ-TV modified and softened their Westinghouse typeface to replace the original logo. The old one was still kept as the secondary logo and is currently seen only in its headquarters in Television Hill (Woodberry).

2017–present
While keeping the stylized "13", the logo was changed to a silver-and-gold color for the logo with the "WJZ" call letters placed in squares (similar to its sister station, WBZ-TV)
