Weekdays begin with The Vinnie Penn Project, a wake-up talk and interview show shared with co-owned WELI in New Haven, which also supplies Connecticut news briefs for WPOP.

Weekends also feature several syndicated shows: The Glenn Beck Radio Program, The Weekend with Michael Brown, At Home with Gary Sullivan, Rich DeMuro on Tech, The Jesus Christ Show with Neil Saavedra and Handel on the Law with Bill Handel, all syndicated by Premiere Networks, co-owned with WPOP by iHeartMedia.

[8] In 1941, with the enactment of North American Regional Broadcasting Agreement (NARBA), the station switched to its present frequency of AM 1410.

[12] In October 1953, Yankee Network parent General Teleradio and The Hartford Times announced that WONS and WTHT would merge, using the WONS facilities and license, in connection with the stations dropping their competing bids for television channel 18 in favor of a single application.

[16] The following year, what had become RKO Teleradio Pictures sold WGTH radio to H. Scott Kilgore's Tele-Broadcasting Inc., for $250,000, adding it to a group that included WKXL in Concord, New Hampshire; WARE in Ware, Massachusetts; WKXV in Knoxville, Tennessee; and KUDL in Kansas City, Missouri.

[17][18] As network programming moved from radio to television, WGTH switched to a middle of the road format.

[21] The station achieved its highest level of success during this era, as it vied with rival WDRC for youthful listeners in the Hartford radio market.

In August 1972, January Enterprises, the company owned by entertainer and TV talk show host Merv Griffin, announced its $2.75 million purchase of WPOP.

[28] SFX Broadcasting announced its $223.25 million purchase of Liberty on November 15, 1995; it immediately resold the Hartford stations, along with WMXB in Richmond, Virginia; WSNE, WHJY, and WHJJ in Providence, Rhode Island; and WGNA, WGNA-FM, WPYX, and WTRY in Albany, New York, to Multi-Market Radio.

[35] Capstar and Chancellor Media announced in August 1998 that they would merge (Hicks, Muse, Tate & Furst was also a major shareholder in Chancellor);[36] upon the merger's completion in July 1999, the combined company was named AMFM Inc.[37][38] AMFM was in turn acquired by Clear Channel Communications (forerunner to iHeartMedia) in a deal announced on October 4, 1999,[39][40] and completed in August 2000.

[41] On January 27, 2012, a second Clear Channel station in the Hartford market began carrying ESPN Radio: WPKX (97.9 FM), previously a country music outlet for Springfield, Massachusetts.

[42] The FM station eventually changed its call letters to WUCS, with the "CS" standing for "Connecticut Sports".
