In 1959, WMAR-TV teamed up with WBAL-TV (channel 11) and WJZ-TV (channel 13) to build the world's first three-antenna candelabra tower. The new tower was built on the newly named "Television Hill" (formerly known as "Malden Hill") in the Woodberry neighborhood of Baltimore, which significantly improved the station's signal coverage well beyond Central Maryland. During the 1970s, the FCC tightened its cross-ownership rules, eventually barring common ownership between a newspaper and a television or radio station in the same city without a waiver. However, the combination of the "Sunpapers" and WMAR-TV was one of several that were "grandfathered" under these rules.
