History

WJZ began operations during the early era of broadcasting amid contemporaries like KDKA (AM), WGY (AM), WBZ (AM), and WOR (AM), at a time when the Radio Act of 1927 and the Federal Radio Commission reshaped licensing. Under ownership ties to Westinghouse Electric Corporation, WJZ became part of pioneering network experiments with NBC and later realignments involving CBS and ABC. During the Great Depression and New Deal years the station carried programming related to Franklin D. Roosevelt and national policy messaging similar to broadcasts on WEAF and WABC (AM). In the World War I and World War II eras WJZ participated in war-related news coverage alongside outlets like Associated Press, United Press International, and Mutual Broadcasting System. Postwar shifts in the 1940s and 1950s paralleled the emergence of television outlets such as WBAL-TV, WMAR-TV, and WSB-TV, prompting radio format evolution. The station underwent format changes during the 1970s energy crisis and the deregulation period under the Telecommunications Act of 1996, with corporate transactions involving companies like Group W, Infinity Broadcasting, Viacom, CBS Corporation, and ultimately Audacy, Inc..

Murrow and Walter Cronkite.

Public affairs and investigative segments have intersected with topics related to institutions such as Johns Hopkins University, Baltimore Police Department, Maryland General Assembly, and cultural events like the Preakness Stakes. Special programming has featured commemorations tied to Baltimore Orioles, Baltimore Ravens, and civic observances connected to Fort McHenry and Star-Spangled Banner history.

Technical information

WJZ operates with a directional antenna system using multiple towers to control coverage across the Baltimore–Washington corridor, sharing engineering practices with stations like WTOP (AM), WBZ (AM), and WABC (AM). Its transmitter facilities employ licensed parameters regulated by the Federal Communications Commission, using nighttime directional patterns to protect co-channel stations such as KTRS (AM) and WCKY. Technical upgrades over decades mirrored industry shifts from vacuum-tube transmitters used by pioneers like Lee de Forest and Reginald Fessenden to solid-state transmitters and digital processing equipment from vendors akin to Harris Corporation and Nautel. WJZ has adopted studio-to-transmitter links, STL encryption, and remote broadcast technologies also utilized by Radio Free Europe/Radio Liberty and BBC World Service bureaus, and participates in emergency alerting systems coordinated with National Weather Service and Federal Emergency Management Agency protocols.
