On June 28, 1935, the station first signed on at 1380 kilocycles as WMFE in New Britain, Connecticut, about 10 miles southwest of Hartford. The station, owned by the State Broadcasting Company, began as a daytimer powered at only 250 watts, although its power increased to 1,000 watts, operating full-time, several years later. The station was an affiliate of the NBC Blue Network and changed its call sign to WNBC in 1936. In 1941, with the enactment of North American Regional Broadcasting Agreement, the station switched to its present frequency of AM 1410. Power was boosted to the current 5,000 watts, and it moved its city of license to Hartford. It changed its call letters to WHTD to reflect its move to HarTforD, and became affiliated with the Mutual Broadcasting System. In 1956, as network programming moved from radio to television, WHTD switched to a middle of the road format. It changed its call sign to WPOP, signifying that it played POPular music. WPOP was a highly rated Top 40 radio station during the 1960s and early 1970s. The station achieved its highest level of success during this era, as it vied with rival 1360 WDRC for youthful listeners in the Hartford radio market. WPOP was acquired by entertainer and TV talk show host Merv Griffin in 1973, who also owned 104.1 WIOF. In June 1975, WPOP dropped its hit music format, switching to All-News, carrying NBC's News and Information Service, with a sizable local news staff covering Connecticut news stories. When the NIS network ended two years later, WPOP continued the All-News format using its own anchors supplemented by CBS Radio News and the Associated Press radio service. By the late 1980s, talk shows were added and the station cut back on its news segments. Affiliation switched from CBS Radio to ABC Radio's Information Network. In 1994, Merv Griffin sold the station to SFX Broadcasting, Inc., which also owned FM 105.9 WHCN. On January 13, 1997, SFX Broadcasting switched WPOP's format to all-sports; most of its programming was provided by One-on-One Sports, but it also carried The Fabulous Sports Babe and weekend programming from the ESPN Radio Network, based in nearby Bristol, Connecticut. The station ended its One-on-One Sports affiliation on February 28, 1999, becoming a full-time ESPN Radio affiliate. In 2000, WPOP and WHCN were bought by Clear Channel Communications, the previous name of iHeartMedia, Inc. On January 27, 2012, WPOP's sports format began simulcasting on co-owned FM 97.9 WPKX, previously a country music outlet. The FM station eventually changed its call letters to WUCS, with the CS standing for Connecticut Sports. WPOP switched from ESPN Radio to Fox Sports Radio on March 5, 2012, with ESPN Radio remaining on WUCS. On August 17, 2015, WPOP changed its format from all sports to a mix of talk and sports, branded as "News Radio 1410". In 2019, it added an FM translator, W265EB at 100.9 MHz, so listeners in Hartford and its adjacent suburbs could hear the station on FM as well as AM radio.
