The station began operation in 1959 as WDHF, owned by hi fi systems and record store owner James Dehaan. The station operated out of Dehaan's store in the Evergreen Plaza in Evergreen Park, Illinois. Its transmitter and tower was in Oak Lawn at 97th and Central. WDHF and Dehaan's record store moved to 102nd and Western Avenue, Chicago, in 1961. In the mid 1960s comedian Bob Newhart purchased the station and moved its studios downtown to 108 N. State St. In the late 1960s, WDHF was sold again to the National Science Network. In the early 1970s, the station's transmitter was moved to the John Hancock Building on the near north side of Chicago. Under Dehaan's, Newhart's and the National Science Network's ownership, WDHF aired a big band music format. Metromedia would buy the station by the early 1970s and flipped the format to a full service station playing middle-of-the-road popular music. Within a few years, WDHF adopted a top 40 format. On December 1, 1976, WDHF's call letters were changed to WMET, while keeping a top 40 format. Several months after the format flip of WEFM from Classical to Top 40 "WE"-FM in 1978, Metromedia flipped WMET to an AOR format. Ratings were good into the early 1980s.
Metromedia would buy Field Communications's TV station WFLD 32 in 1983. In March 1986, though, Metromedia sold all their TV stations, including WFLD-TV, which was later owned by Fox, and restructured and became Metropolitan Broadcasting. They at that time sold WMET to Doubleday Broadcasting, which altered the format to "Rockradio," the new WMET. In January 1985, WMET was flipped to a highly unsuccessful mid-tempo AC for a short while. Then the calls were briefly changed to WRXR, and the format became an oldies/classic hits hybrid.
In the fall of 1986, a New Age music show was added in evenings from 7 p.m. - midnight. Shortly after, WRXR was sold to Pyramid Broadcasting. The New Age music was added in overnights by the spring of 1987.
On August 3, 1987, the station's call letters were changed to WNUA as a full-time New Age broadcast began (which is believed to be the source of the call letters). Indeed, for a time the station's slogan was "Music For a New Age". Initially the station only played New Age music but by the Winter of 1988 it added smooth jazz music before 7 p.m. during the day. The station at that point was still all instrumental.
By the Summer of 1988, the station added four vocals per hour during the day. The vocalists were R&B artists, soft hits by rock artists, and a few AC cuts. By 1989, the station was about half vocals and half instrumentals during the day and still all New Age instrumentals at night.
By 1990, the station began to grow and attract many listeners. Smooth Jazz and a couple vocalists per hour at nights were also added. During the day, vocals were pulled back to about 1/3. New Age music was being played less than before. As a Smooth Jazz station, WNUA had become a major pioneer in the format, spawning imitators in other cities, such as KMYT in Temecula, California. KMYT uses the same on-air jingles as WNUA, which mentions the call letters first and the frequency second (sung as "WNUA 95.5" and "KMYT 94.5"). Some former smooth jazz stations, such as KKSF in San Francisco, California, WSMJ (104.3 FM) in Baltimore, Maryland, WSJT in Tampa, Florida, WZJZ in Fort Myers, Florida and WJJZ (106.1 FM) in Philadelphia, Pennsylvania, also used these jingles, and the new WJJZ (97.5 FM), also in Philadelphia, would use exactly the same jingles as a tribute to the old station's heyday, after originally using different-sounding ones that could easily be told from those of its predecessor. (It should be noted, though, that the new WJJZ's jingles used a slightly different arrangement, as they were last sung as "WJJZ 97-5," omitting the "point" that was included in the 106.1 version.) KYOT-FM (95.5 FM) in Phoenix, Arizona, sometimes uses the jingles as well, but its identity is never sung. Prior to a format change in January 2009, WJZZ (107.5 FM) in Atlanta, Georgia (now WAMJ), used similar jingles that mentioned the frequency before the callsign, thus sung as "107.5 WJZZ". The jingles were used for the Smooth Jazz Network until 2012.
In 1994, Pyramid sold WNUA to Shamrock Broadcasting, which would merge with Chancellor in 1995 and merge with Evergreen in 1997. WNUA was then owned by Chancellor, which restructured as AMFM Inc. in 1999. In 2000, AMFM merged with Clear Channel Communications, making WNUA a Clear Channel station.
WNUA was the home of the now-defunct Ramsey Lewis morning show, and it was also where he recorded his syndicated show, Legends of Jazz (which showcased the music of instrumentalists Charlie Parker, Oscar Peterson and Miles Davis, as well as vocalists Louis Armstrong, Billie Holiday and Ella Fitzgerald) for distribution to other smooth jazz stations across the nation. The show lived on in Chicago on WLFM-LP during that station's run, and continues on smooth jazz stations across the country.
In late 2006, three Smooth Jazz personalities, WNUA's Ramsey Lewis, Annie Ashe, and Dave Koz were tapped by Broadcast Architecture to syndicate their respective shows on its Smooth Jazz Network. Lewis's morning show aired in other parts of the country for the first time. Ashe hosted the night time show, known locally as the now-defunct "Lights Out Chicago," for approximately two months; however, in December 2006 the show reverted to its local format as Danae Alexander was moved back to the 7 p.m.-12 a.m. slot after being in the afternoon slot for the past year. As of the first of the year, the afternoon slot was hosted via syndication by Dave Koz, the well-known saxophonist regularly featured on smooth jazz radio stations.
WNUA won R&R Smooth Jazz Station of the Year, 1998–2005, and was a recipient of the Marconi Award for Smooth Jazz Station of the Year, 2004.
Rick O'Dell was the program director until mid-January 2009. Glenn Cosby was his replacement.
Switch to Spanish 
On May 22, 2009, at 9:55am, after David Sanborn's "Chicago Song", WNUA flipped formats to Spanish contemporary as Mega 95.5 to cater to Chicago's Hispanic community. It competed with WPPN for the younger Spanish speaking Hispanic audience in addition to its English sister station WKSC which is heavily targeted towards the Hispanic population.
The Smooth Jazz format was picked up a few hours later by television station WLFM-LP (Channel 6) by audio available through a technical quirk within Chicago proper on 87.7 FM, but in October 2010, the format was tweaked to a Smooth AC hybrid. "Smooth 87.7" featured several former WNUA smooth jazz hosts during the day on weekdays, and aired Broadcast Architecture's Smooth AC Network the remainder of the time. On April 30, 2012, Merlin Media, LLC took over the station, changed the format to a simulcast of Merlin's all-news station, WIQI, followed by a call sign change from WLFM-LP to WKQX-LP, and another format change to alternative rock. On May 3, 2012, Merlin added a satellite-fed version of Broadcast Architecture’s "Smooth Jazz Network" format on the HD3 subchannel of its WLUP-FM (97.9-HD3), but this was later changed to Smooth AC as well.

Shift to Regional Mexican 
On June 19, 2012 Mega 95.5 shifted to a Regional Mexican format known as El Patrón 95.5 to more directly compete with WLEY and WOJO instead of sister stations WKSC and to a lesser extent WLIT and CBS Radio's WBBM-FM. The shift was affected by low ratings from the previous Spanish Language Hot AC format.
