WBZ-TV first signed on the air on June 9, 1948, as the only television station that was built and signed on by the Westinghouse Broadcasting Company, and as a primary NBC affiliate on VHF channel 4, which its radio station of the same name was also long associated with the Red Network.

Early logotype (c. 1960)
The logo design, especially the font (called "Westinghouse" or "Anklepants" (due to a similar typeface) by some people), was originally introduced when then-owner Westinghouse Broadcasting (Group W) introduced its design language in 1963.
In 2018, this iconic "4" was revived to celebrate its 70th anniversary.

WBZ would also debut a new tagline called The Tradition Continues when it switched to CBS that year. Westinghouse would later acquire CBS, making WBZ-TV a O&O.
