WLUP-FM (97.9 FM, "The Loop") is a commercial classic rock radio station serving the Chicago metropolitan area. Owned and operated by Merlin Media, LLC, WLUP transmits its signal from an antenna located atop the John Hancock Center in Downtown Chicago at a height of 1,390 feet (420 m) with an effective radiated power of 4,000 watts. WLUP can be heard as far away as Kalamazoo, Michigan, which is 90 miles (140 km) from Chicago. WLUP also airs HD Radio programming on two subchannels: 97.9-HD2 airs a comedy format called "Loop Laffs", while 97.9-HD3 airs a locally produced Smooth Jazz/Soft AC hybrid format.

Frequency use prior to WLUP 
WLUP's first call letters in the 1950s were WEHS, which was originally owned by Evanston Township High School in the 1920s. Richard Hoffman, owner of WHFC, in the early 1930s bought out two radio stations which shared the 1420 kHz frequency of his station: WEHS and WKBI. He revived the WEHS call letters in the late 1940s for a new FM station. WEHS broadcast background music for National Tea Grocery stores in the Chicago area. When the contract with National ran out in the mid-1950s, WEHS simulcast WHFC-AM's foreign language and black programing for six hours a day, the minimum broadcast time to keep the license. When the Chess Brothers purchased WHFC and changed its call letters to WVON (We're the Voice of the Negroes), they changed the WEHS call letters to WHFC(FM). The station (97.9FM) then simulcast WVON (1450AM) 24 hours a day. In the mid-1960s, the station began airing separate programming as WSDM (We're Smack Dab in the Middle of the FM dial). They also briefly used the term "Stereo Den for Men"; the format featured all female announcers (Yvonne Daniels and Dr.Cody Sweet among others) playing light jazz and instrumental music. This light jazz & instrumental format was similar to the more recent "Smooth Jazz" formats. In the 1970s, WSDM began to mix album rock music with its light jazz. Although WVON was sold to the Potter Palmer family in the late 1960s, the Chess family held on to WSDM, which was being run by one of Chess' sons.
Owned by the Chess family of Chess, Checker and Cadet Records fame, through their company, L & P Broadcasting. "L" stood for Leonard Chess, who primarily ran the record labels and recording studio, while brother Phil Chess ("P") was president of the radio company. Son Terry Chess was General Manager of WSDM through much of the early and mid-1970s. The WSDM call letters acronym stood for "Smack Dab in the Middle", "the middle" meaning the exact middle of the FM radio dial. The radio station positioned itself as "jazzed up rock" and the "station with the girls" — a reference to the all-female air talent. Its original program director was Burt Burdeen. Among the disc jockeys were Connie Szerszen, Cindy Morgan (who later left radio, went to Los Angeles and became an actress, her career including roles in such films as Caddyshack and Tron), Danae Alexander, Linda Ellerbee, Yvonne Daniels, Dr. Cody Sweet, Kitty Loewy, Susan Payne, Janice Gears and Glorie June. There were guys on "the station with the girls", too. Announcers such as David Witz (cousin of former WCFL General Manager Lew Witz) and Don Davis (later an air talent on WDAI/Chicago and then a Program Director for DC-101 in Washington, D.C. and WCKG-FM in Chicago) appeared on WSDM in the mid-1970s. Davis made the transition from WSDM to the WLUP airstaff when the format changed in 1977.
The call letters changed to WLUP in March 1977. The station called itself "The Loop" which is what the main business district in Chicago is nicknamed. WLUP programmed a low-key female-friendly AOR format (similar to today's classic rock formatted 97.1 The Drive).) Jay Blackburn was Program Director and Tom O'Toole served as the stations first morning host and was the first Loop DJ to sign on the air. The original Loop air staff included O'Toole in mornings, Captain Billy Martin in middays, Les Tracy in afternoon drive, Greg Budell evenings, and Don Davis overnight.
Congressman Cecil Heftel (from Hawaii) purchased the radio station in early 1979, kept the call letters, and "Loop" identifier. Lee Abrams was hired as consultant. The rock format was kept in place, but emphasis was put on harder-edged rock. Steve Dahl, who had been unemployed since WDAI (94.7) went to a disco format in December 1978, becoming the basis for one of the most infamous promotions in sports history, Disco Demolition Night, was hired for mornings in March 1979. Overnight disc jockey Matthew "Mondo" Meier was teamed with Dahl to do news. He started using his real first name "Garry". Garry became Steve's full-time sidekick when Buzz Kilman was hired as the newsman in 1980. Chuck Swirsky provided sports reports. Steve and Garry were fired in 1981 for "assaulting community standards". A series of morning men including Matt Bisbee, Mark McEwen (who later gained national fame as a CBS network TV weatherman), and the team of R.J. Harris and Pat Still tried their hand until Jonathan Brandmeier was hired in April 1983. Kilman remained as newsman and Bruce Wolf replaced Swirsky when he went to WGN in 1981. Steve and Garry returned in 1986 to host afternoons.
In 1985, Heftel Broadcasting bought AM 1000 WCFL, which was once a powerful CHR (Top 40) station, but then became a Christian music and teaching station. In April 1987, that station became WLUP "The Loop" as well as making the FM station WLUP-FM. The religious format was dropped from 1000 WLUP and the station simulcast WLUP-FM overnights. During the day, though, WLUP 1000 ran a full service rock format while focusing on talk. By 1990, the AM station would evolve to mostly talk with a few rock songs mixed in per hour.
WLUP-FM also began mixing more talk into the format by simulcasting the AM station, and evolved to a Talk/Comedy format by 1993. Shortly after, the AM station became a sports station as WMVP. WLUP-FM became WLUP again, and evolved to a talk format with a few rock songs mixed in per hour.
WLUP was one of the first stations to have the "FM talk" or "hot talk" (comedy/talk) format in the early 1990s. Some of the shows were Steve Dahl and Garry Meier, Danny Bonaduce, Liz Wilde, Kevin Matthews, Jonathon Brandmeier, with News-man/Blues-man Buzz Killman, Ed Schwartz and Seka.
By the early 1990s, Heftel had acquired a lot of Spanish radio stations. Its English speaking stations were sold off one by one, and WLUP-FM was sold to Evergreen as a result. Evergreen kept the talk/comedy/rock format, but only for a short time. WLUP switched to a modern rock/Hot AC format late in 1996. In 1997, Evergreen and Chancellor merged. Evergreen opted to sell WLUP to Bonneville in July (which already had a modern rock/Hot AC outlet in WTMX), and then switched WLUP to a classic rock format. Brandmeier left WLUP and Kilman became the morning man for a brief period before he rejoined Johnny B. at WCKG. In June 1998, WLUP adopted the slogan, "Classic Rock That Really Rocks". During this period, full-time on air personalities included Steve Downes, Pete McMurray, Seaver, Sari, Cara Carriveau, Scott Loftus, Jimmy Novak, and Mark Zander.
Emmis Communications traded three of their stations in Phoenix to Bonneville for WLUP-FM and $70 million in 2004. While under Emmis ownership, WLUP slowly evolved into a mainstream rock format, while continuing to lean on classic rock with a harder edge. This prompted for former sister station WDRV to acquire the classic rock format and for rival WZZN (now WLS-FM) to switch from active rock to oldies in 2005.
In 2005, Emmis hired Zakk Tyler to host afternoon drive as the station evolved into a more "personality-driven" format.
Also in 2005, Emmis brought back Jonathon Brandmeier to do mornings on The Loop again.
On January 15, 2007, Chicago's NBC owned and operated station, WMAQ-TV channel 5, began a new weekday morning show called ''Barely Today which airs from 4:30–5 a.m. The new morning show was simulcast on WLUP-FM and hosted by Bruce Wolf, who was the former weekday morning traffic/sports anchor for WMAQ.
On September 8, 2008, Emmis announced a programming partnership with WorldBand Media and used WLUP's HD3 signal to produce programming for the South Asian communities in 3 major cities, including Chicago. The South Asian format, known as HumDesi Radio, became available on the HD-2 signal of alternative-rock sister station WKQX.
By 2011, WLUP shifted completely to a classic rock format.
On May 3, 2012, Merlin added a satellite-fed version of the smooth jazz format on WLUP's HD3 subchannel (97.9-HD3). As of July 2012, the syndicated Broadcast Architecture Smooth Jazz feed has been dropped and replaced with a locally produced, automated Smooth AC format featuring a wide mix of music from Frank Sinatra to The Jackson Five in addition to instrumental contemporary jazz.
Sale to Merlin Media 
On June 21, 2011, Emmis announced that it would sell WKQX, sister station WLUP-FM, and New York's WRXP to Merlin Media, a group headed by former Tribune Company executive Randy Michaels. Emmis, who would retain a minority stake in Merlin Media, would grant Merlin a local marketing agreement to operate WKQX and WLUP-FM from July 15 until the sale to Merlin officially closed on September 1.
In 2009, Jonathan Brandmeier exited WLUP. Byrd, previously on middays, moved into morning drive and weekender Pat Capone took over Byrd's midday time slot. Pete McMurray also took over the 7 pm to 12 am shift. Brandmeier is now at WGN.
Radio personality Maxwell (Benjamin Bornstein), best known for his years as host of The Maxwell Show at WMMS/Cleveland, took over as the WLUP-FM morning host on July 30, 2012. Former personality Zakk Tyler (Dominic Zaccagnini) was also hired to return to WLUP.
Weekend and substitute DJs include Tom O'Toole (the first WLUP DJ to sign on), Mike Noonan, Pat Capone, Alan Daley, and Don Nelson.
Theme shows include:
- Two-Fer Tuesdays (two songs from the same artist, every Tuesday, all day)
- 97 @ 9 (97 minutes of commercial-free music, every weekday at both 9am and 9pm)
Some of the former theme shows include:
- Get The Led Out (a three-song set of Led Zeppelin songs that aired weeknights at 8 pm)
- Saturday Night Rock of the '80s (an all-'80s rock music show that aired from 7-9pm)
- LOOP On-Stage (a full hour of live rock music that aired at 10 pm on Friday nights)
"Saturday Night Rock of the '80s" was originated by one-time Night and Overnight DJ Zander in 2003. He brought the show over from WCKG where he created it in 1997, and later took it to WXXY (The 80's Channel). He now is heard on "the Rockin' 80's" airing over 45 stations in North America.
Dr. Demento was carried on WLUP from 1987 through 2010, just prior to when Dr. Demento ceased terrestrial broadcasting.
Advertising and promotion 
In the early 1990s, WLUP aired a popular television commercial featuring a fat man dubbed "Joey Bag O' Donuts" dancing to Aerosmith's "Walk This Way". In the time span since the original commercial was aired, the footage of the dancing fat man in the commercial has been used by numerous other radio stations across the country. The original WLUP commercial was re-created in the mid-late 2000s and briefly featured Kelly the Loop Rock Girl.
On April 25, 2008, The Loop crowned its first ever Rock Girl Roadie winner, Mike Gentile, a paramedic, from Westchester, IL, at the Loop Rock Girl Finals at Austin's Saloon in Libertyville. Gentile got to shadow the station's 2008 spokesmodel, Kelly, also known as The Loop Rock Girl, for an entire year as she went onstage for band introductions, backstage to meet musicians, or in the front row of the audience to watch the show. Gentile kept a detailed blog for The Loop's Web site about all of his experiences. Gentile gained local celebrity status when he hosted a Hometown Tour pilot with 97.9 "The Loop's" Mid-day radio personality Erin Carmen and with a highly viewed video featuring the 2008 Loop Rock Girl, Kelly, getting guitar lessons from Mike. In the video, Kelly hinted that there would be a series of videos showing her progression.
