History of Philadelphia radio station 93.3 WMMR


WIP-FM

On February 11, 1941, the Federal Communications Commission granted Pennsylvania Broadcasting Company a construction permit for a new FM station on 44.7 MHz on the original 42-50 MHz FM broadcast band with the W47PH call sign. The construction permit was modified on November 4, 1941 when the FCC reallocated the station to 44.9 MHz with a corresponding call sign change to W49PH. The station signed on the air April 20, 1942 with a simulcast of its sister station WIP 610 AM’s middle of the road (MOR) format. On November 1, 1943, the station was assigned the WIP-FM call sign, and in 1947 the FCC reallocated the station to 93.3 MHz.

In the 1950s and 1960s, WIP-FM continued to simulcast WIP AM’s full service MOR format of music, news, sports and talk for all or part of the day. (In 1967, it was only simulcasting from midnight - 6AM) Original programming on WIP-FM was also MOR and easy listening, but using announcements from the AM disc jockeys. In 1962, the station’s antenna was moved from 35 South Ninth Street to the top of the PSFS building.

WMMR

Original WMMR logo The station was purchased by Metropolitan Broadcasting in 1959, which was a spin-off of the defunct DuMont Television network. Although Metropolitan Broadcasting changed its name to Metromedia in 1961, it continued to use the Metropolitan name for its broadcasting division until 1966. At that time, the station changed its call sign to WMMR to reflect the new Metromedia name. (From 1948 to 1993 a local student-run carrier current radio station at the University of Minnesota used the slogan “WMMR” though unofficially.) The WIP calls would reappear on the FM dial some 40 plus years later on 94.1 after WIP-AM changed hands many times.

Progressive rock

Marconi Experiment ad In 1968 WMMR sister stations KSAN-FM San Francisco and WNEW-FM New York found major success with the progressive rock format, which was a freeform format consisting of many types music including rock that was meaningful to the youth culture of the day. However, WMMR only gradually embraced this format, starting with Dave Herman’s show dubbed the “Marconi Experiment”. The first song played on the show was “Flying” by The Beatles. Over the instrumental song, Herman recited these words: “Arise my heart, and fill your voice with music. For he who shares not dawn with his song, is one of the sons of ever darkness.” This was known as “The Incantation” and continued as the regular show opening. Initially the show aired daily from 8PM until Midnight while the rest of the day’s programming could be described as easy listening or MOR, including shows such as Jack Rattigan’s “Sinatra and Company”. As the Marconi Experiment gained popularity in audience numbers and sales, it was expanded to 9PM to 2AM in the fall of 1968.

Former WIBG host Jerry Stevens arrived at the station as Program Director in September 1969 (after a stint at WNEW) and further experimented with the station’s format, which evolved into a full time progressive one later that year, finally displacing the remaining “Sinatra-type” music. A survey commissioned by the station in 1970 found that WMMR was the most listened to station in the last 24 hours on the local college campuses of The University of Pennsylvania, Temple and Villanova.

Michael Cuscuna, from the University of Pennsylvania’s WXPN, replaced Herman in 1970, but was quickly hired away by WABC-FM (now WPLJ) in New York. Michael Tearson, also from WXPN, replaced Cuscuna and remained a mainstay at WMMR for over 20 years. Herman went to WABC-FM and then for a couple of decades on WNEW-FM, and later on WXRK. Tearson later worked at WMGK in Philadelphia, from April 2002 until January 2013. He was also heard on Sirius XM’s Deep Tracks channel. Lyn Kratz, often known as the “Diva of Darkness”, did a late-night show from 1975-1980 and again from 1984-1996.

Several Philadelphia FM stations tried to compete with WMMR in the late 1960s, including WIFI and WDAS-FM. Neither station stayed with the rock format for long. In 1970, WIFI switched to a Top 40 format, while WDAS-FM changed format around 1971 to a varied album oriented R&B. Later in the 1970s, two other Philadelphia radio stations briefly became competitors: WYSP (formerly WIBG-FM) and WIOQ.

One of WMMR’s most influential disc jockeys during the 1970s was Ed Sciaky, who was known for playing and boosting the careers of new artists such as Billy Joel and Yes. Sciaky is credited with introducing Bruce Springsteen to Philadelphia, among others. WMMR alumni include David Dye, host of the World Cafe on WXPN and syndicated on many NPR stations. Another former WMMR DJ is Nick Spitzer, now a New Orleans resident and host of “American Routes” on NPR. One-time WMMR midday DJ Dick Hungate later switched to WYSP, pioneering the classic rock format in Philadelphia. Some WMMR DJs such as Dave Herman and Carol Miller would later go onto longtime careers on New York stations.

During the 1970s, the station’s progressive format morphed into album-oriented rock. In the early 1990s they leaned towards classic rock. By the 2000s they programmed a blend of energetic classic rock and up-tempo current rock. Though more oriented toward the heavier end of the music spectrum today than in its earlier days, WMMR continues to play old and new music. Since 2007, the format has been described as active rock.

Studios and ownership

In 1962, sister station WIP AM moved into the Wellington building at 19th and Walnut street, overlooking Rittenhouse Square. WIP-FM, just an afterthought at the time, tagged along for the ride. In 1989, WMMR, by that time one of the city’s top heritage rock outlets, was sold to Group W (Westinghouse Broadcasting) but did not move to the KYW Building at Fifth and Market Street until February, 1992. (“WMMR DJ John DeBella, fellow jock Pierre Robert and an escort of about 30 bikers from the Tri-State Hog Club made the trek on noise-polluting Harley Davidsons, broadcasting every inch of the way.”1)

In 1995, Westinghouse purchased CBS, and then the following year they purchased Infinity Broadcasting, owners of rival WYSP, potentially uniting them as sister stations. However, the purchase put CBS over the limit of the number of stations they were allowed to own in Philadelphia according to the FCC rules at the time. As a result, WMMR was sold to Greater Media in 1997. On Saturday, April 5th, 1997, WMMR and WYSP switched studios. WYSP moved downtown to the KYW building, and WMMR moved out to the suburban Bala Cynwyd offices of Greater Media. In 2016, Beasley Media Group acquired Greater Media and its 21 stations (including WMMR) for $240 million.

John DeBella

WMMR 80s logo John DeBella joined WMMR as morning host in late 1982, succeeding Steve Martorano and Anita. By 1985, the morning show was known as the “Morning Zoo” which dethroned John Harvey (“Harvey in the Morning”) on WIOQ to reach the top spot in morning drive. Other members of the zany cast of the Morning Zoo included Mark “the shark” Drucker, Chip Horaneck and Clay Heery. Some of the more popular events of the Zoo era included the annual “DeBella DeBalls” and Hawaiian Shirt Gonzo Fridays. However, starting in 1986 when Howard Stern began simulcasting on rival WYSP, the Morning Zoo (and WMMR overall) steadily lost listeners. By 1993, Stern had crushed DeBella in the morning ratings. WMMR attempted one last effort to revive mornings in 1993 by pairing DeBella with sportscaster Howard Eskin for a hybrid show known as SportsRock. This effort failed to turn things around and DeBella moved to afternoons, with laid-back WMMR veteran Pierre Robert taking over the morning shift.

In 2005, The Preson and Steve morning show, previously heard on WDRE and WPLY, debuted on WMMR. Pierre Robert moved to middays on WMMR and DeBella now hosts mornings on WMGK.

DO you want to know why ipods are so popular? Because ALL radio stations beat songs to death for a few months and never play variety. THe last I checked, an album has 10+ songs, but all the radio stations play 2 songs from those albums at best. I'd rather listen to KYW and get 24 hour news.....at least the news changes from time to time....

I know Carol Miller went to xm radio but what happened to Johnny Kraft. Errol Bailey used to be on MMR also went to xm radio. My question is where are the disc jockeys from 68-70. Long time MMR listener.

Johnny Craft went back to the suburbs to his wife and baby daughter. Maybe you remember that he played Stevie Wonder's "Isn't She Lovely" the day she was born. Many of us scattered like seeds but are sometimes in touch.

Back in the late 1960s and early 1970s, WMMR featured a program, 'Opus' starting at midnight lasting through till Morning. Easily my favorite all time radio program. I don't see the name of Jonathan Takeoff who was one of the DJs covering a time slot at the same time as Michael Tearson in the late 1960s. There was a lady DJ at the same time, whose name escapes me at the moment. When John Hartford released "Hey Babe you wanna boogie?" and the FM airwaves were playing it during the early 1970s; one night, she played Hartford's song three times in a row. Then she explained that she only played it to satisfy the sickos demanding she play the song; but that she would never play it again. Never heard it during her shift, again. She was just another of WMMR's great DJs. Back, during the late 1960s, WMMR played the greatest WMMR radio commercials. e.g. WMMR played on commercial advising the length to adjust radio antennas for best reception, then after stating "for antennas internal to windshields", one heard the sounds of breaking glass.

I remember Steve(Stevesky) Sutton and the lunch songs he would play at noontime. These were songs from popular artists like the Rolling Stones and the lyrics were changed to fit the lunch time theme. For example, 'Beast of Burden' was rearranged and the lyrics were, "Don't ever leave your pizza burning'. I spent my lunch time on many a day rushing out to my car to turn the radio on to hear this hour of music that Mr. Sutton would play at noon.

Did WMMR EVERY HALLOWEEN rebroadcast the War of the Worlds? Starting when to when. In particular 1970-1971

16. Posted on Saturday, January 19, 2019 by Ron Messner:
I heard War of the Worlds on WMMR FM Halloween 1970. Don't know if it was played any other year. Johnny Craft was and is my all time favorite DJ. Post # 10 - Alana Morris- did the news in the times of " The Radio Station". She ended the news with " I'm Alana Morris and we're WMMR". Almost all on air people said " we're WMMR", except Johnny Craft- he would say "your tuned to FM 93.3, WMMR Phila. I'm Johnny Craft, good morning.

I remember moving to Philly after college in the mid 80s and listening to WMMR at 6am (the start of the morning show) on a Monday and they would introduce the show with a countdown (similart to that before a rocket would be flown into space). In the background you'd hear Debella saying he didn't get enough sleep, etc., etc. Really hilarious---I'm now in Pittsburgh for 25 years and was trying to search for this on youtube. Is there any way I could hear that again----really funny s--t!

I loved steve sutton (way before pierre did the noon shift) when he did the lunch songs too. Does anyone know if you can find them online anywhere?

I am trying to compile a list of local Philly groups from the 1980s. I remember hearing a lot back then but don't remember much now, especially because I don't live in the region anymore. Can anyone add to the list? Hooters Beru Revue A's Robert Hazard and the Heroes I also remember a WMMR music contest and one of the bands was called the Zebras, but I can't find anything on it. Does anyone recall?

My high school years, September 1979 through June 1983, coincided with my ‘MMR listening years. Lunch blocks, Two-fer Tuesday. Left S. Jersey in mid ‘84 to join the Navy, and ended up outside of DC after I got out. But I always will have fond memories of listening to DeBella, Pierre, Joe Bonadonna, and Michael Tearson.

WMMR saved my life in the early 1970s. I was newly divorced (and not yet 21!), living alone and trying to figure out how to live and thrive, and every night in my studio apartment at 20th and Locust, I tuned in to WMMR and felt my soul being restored. The music lives on! Thank you, WMMR, 93.3. You rock!

While living in Philly from 1972 thru 73, can't forget the breakthrough artists of 72, such as Bonnie Raitt , America , Jackson Browne, Billy Joel and the Eagles, all featured on 93.3 WMMR. Not sure about when Yes debuted .
