Owned by St. Peter the Rock Media, Inc., a nonprofit corporation which has applied for 501(c)(3) tax–exempt status with the Internal Revenue Service,[3] WCCR serves Greater Cleveland as the local affiliate for EWTN Radio.

WCCR's studios are located in the Cleveland suburb of Broadview Heights and the station transmitter resides in neighboring Brecksville.

In July 1964, three account executives at WHK Norman Wain, Bob Weiss, and Joe Zingale – quit their jobs to form Westchester Corporation.

When Westchester Corporation saw the growing and devoted listener base that their largely ignored FM station was developing, WDOK was branded "Stereo Cleveland – Beautiful Music for the land of the Western Reserve".

In 1969, Westchester Corporation took the format to the Pittsburgh market, purchasing WMCK in suburban McKeesport, Pennsylvania, and changing the calls to WIXZ.

[6] "WIXY 1260" exists today as an online tribute station based in the Cleveland area airing the original PAMS jingles and classic 1960s and 1970s hits.

[6] Although it never caught on with a large audience, WMGC was home to several of the area's top broadcasters, including general manager Dick Conrad, Program Director Jeff Baxter, and DJs Dan Bradford and Lady J.

During its glory years (July 1981–October 1987), on-air talent, in addition to Davis, included Al James, Tom Armstrong, Bill Randle, Carl Reese, Ronnie Barrett, Dick Conrad, John Webster, Ted Alexander, Joe Black, and Jack Reynolds.

[9] WBBG's call letters (originally stood for "Boys from Bowling Green")[10] soon took the meaning "Big Band Grandstand".

[13] The AM call sign was changed to WMJI on November 24, 1987[14] to match the FM station's (which legally became WMJI-FM for the interim).

After a few months of FM simulcasting, Jacor sold the station to Gore-Overgaard Broadcasting (led by Harold W. Gore and Cordell J. Overgaard), a Christian organization brought a format of religious programming and gospel music.

[14] Under Gore-Overgaard ownership, the station received permission to double its daytime power from 5,000 to 10,000 watts, although the upgrade was not accomplished until Divine Mercy Communications, Ltd. purchased and installed the new transmitter provided for in the license change.

[15] The station inaugurated its new format on February 22 by broadcasting a noon mass live from St. John's Cathedral celebrated by Bishop Anthony Pilla.

In addition, the station produced live daily mass from St. John's Cathedral and carried regular installments of the English versions of Vatican broadcasts.
