➦In 1921..Boston's WBZ radio, which now broadcasts at 1030 kHz AM and is the oldest surviving commercial radio station in New England, signed-on broadcasting from Springfield, MA.
The station has long been one of the highest-rated stations in the Boston area, and covers much of the eastern United States and Canada at night with its 50,000-watt clear-channel signal from its transmitter location in Hull, Massachusetts, which has been used by the station since 1940. The transmitter is a two tower directional array where each tower is 160 meters (520 ft) tall. The signal is intentionally directionalized from their coastal location for maximum power transmitted into the continental United States, giving WBZ outstanding multi-state coverage after sunset.
WBZ's initial license, for operation in Springfield, was issued by the Department of Commerce to the Westinghouse Electric & Manufacturing Company on September 15, 1921; it was the first license to specify broadcasts on 360 meters (833 kilohertz), and was subsequently deemed to be the first license for a commercial broadcast station. However, other stations, such as WWJ in Detroit, 1XE/WGI in Medford Hillside, and sister station KDKA in Pittsburgh, were already broadcasting under different license classifications.

| Original Studio on Page Blvd. |
The station's original transmitter and studios were located at the Westinghouse factory on Page Boulevard in East Springfield. However, WBZ's
inaugural program, on September 19, 1921, was a remote broadcast from the Eastern States Exposition in West Springfield.
The original format was general entertainment and information, which included live music (often classical music and opera), sports, farm reports, special events, and public affairs programming. Despite WBZ being housed in Springfield, it somewhat difficult to attract top-flight artists to the station, leading Westinghouse to open a studio at the Hotel Brunswick in Boston on February 24, 1924. WBZ also expanded its news programming via a partnership with the newspaper Boston Herald and Traveler. It also carried a considerable amount of sports broadcasts, including Boston Bruins hockey, Boston Braves baseball, and Harvard Crimson football.
Because of its comparatively wide reach, the station often referred to itself as "WBZ, New England" as opposed to associating itself solely with Springfield or Boston.
However, even after several power boosts (the station broadcast at a power of 100 watts in 1921, but was using 2,000 watts in April 1925, the station still had some trouble reaching Boston, leading Westinghouse to sign on WBZA, a 250-watt station at 1240 kHz, on August 20, 1925. Efforts were soon made to operate WBZA as a synchronous repeater of WBZ, by then at 900 kHz; this process was difficult, as the two transmitters often interfered with each other even in Boston, and WBZA went back and forth between the two frequencies for nearly a year before finally going to full-time synchronous operation in June 1926.
