Owned by the International Church of the Grace of God, the WBIX studios are located in the Boston suburb of Somerville, while the station transmitter resides in Quincy, on the southern banks of the Neponset River near the Southeast Expressway.

The station gave its first broadcast on July 31, 1922, as WNAC, founded by Boston businessman John Shepard III.

On January 4, 1923, using a 100-foot antenna connected by a clothesline to the building's roof, WNAC arranged the first network broadcast in radio history with station WEAF in New York City.

[23] In 1931, Shepard purchased a second Boston station, WAAB, which became an affiliate of the Mutual Radio Network in 1935, a year after MBS was formed.

In 1942, to comply with anti-duopoly regulations established by the Federal Communications Commission, WAAB was moved to Worcester, about 40 miles west of Boston.

In addition to WNAC and the two networks, the sale included WEAN, WAAB, WICC in Bridgeport, Connecticut; and experimental FM stations in Paxton, Massachusetts, and Mount Washington, New Hampshire.

[34] In 1947, the FCC denied a request to allow WNAC to move to 1200 kHz and boost its power, using a directional 50,000-watt transmitter.

Vic Diehm and Associates subsequently changed 1260 AM's calls to WVDA and launched a new format on the station, using WLAW's former studios in the Hotel Bradford in Boston.

The station was sold in 1957, to Great Trails Broadcasting Corp., owned by former Truman administration Commerce Secretary Charles Sawyer, for $252,000.

It carried hourly newscasts, some feature programs, special news events, but very little of the network's Monitor weekend service.

During the "Wonderful World Of Music" days, live announcers spoke only every fifteen minutes, to run down what had been played during the previous quarter-hour, read commercials, and give weather updates.

Carlin wrote that another future comedian, Jack Burns, also worked there as an announcer and newscaster at the station during this time.

Known as "Z 1260", WEZE was then in direct competition with established top 40 AM stations WRKO (680 AM), WMEX (1510 AM), and WVBF (105.7 FM, now WROR-FM).

Perhaps the best-known announcer during this period was Alan Colmes, who replaced Chuck Kelly in the morning drive slot and who later co-hosted a talk show with Sean Hannity on cable TV's Fox News Channel.

From August 1975 until early 1977, WEZE tried "The Wonderful World Of Music" again (which was often branded "The Easiest Sound In Town" in newspaper ads, billboards, and television commercials).

This format, promoted as "AlbuM 1260" (stylized to denote its frequency as "AM 1260"),[44] continued until the 1978 sale of the station to New England Continental Media.

Salem exercised an option to acquire WBNW (590 AM) in the fall of 1996, and that December, began a simulcast that resulted in WEZE's call sign and programming moving to 590 kHz.

The Praise 1260 format included programs that Salem lacked the time to air on WEZE, along with about 6 hours a day of rhythmic Christian music.

(The Praise 1260 format was dropped earlier in that fall in preparation for the sale, and in the interim, WPZE returned to simulcasting WEZE).

It carried syndicated talk shows from the Salem Radio Network, including Hugh Hewitt, Mike Gallagher, Michael Medved, Larry Elder, Eric Metaxas, and Dennis Prager, and business programs, including Ray Lucia from the Business Talk Radio Network.
