The WLS Radio Timeline Page


In The Beginning....

    WLS radio began transmitting on April 12, 1924 with the call letters WBBX. The first test program was from the studios of WMAQ from the Tower Studio on April 9,1924 using the call letters WES (World Economy Store). Sears, Roebuck and Company located in Downtown Chicago, owned WES but on April 12th they changed the call letters to WLS (Worlds Largest Store).

    Known as the Prairie Farmer Station, WLS captured an audience of midwest farmers. Shows focused on agricultural information. The WLS Barn Dance was created by George Hayes in 1924. He was a Memphis announcer who worked at WLS.

    In the 1930's to early 1940's, two of many programs heard on WLS were "Fame and Fortune" with Tommy Dorsey and "Pot o Gold" with Horace Height.

     On MAY 6, 1937, the German airship Hindenburg burst into flames 200 feet over its intended landing spot at New Jersey's Lakehurst Naval Air Station. Thirty-five people on board the flight were killed (13 passengers and 22 crewmen), along with one crewman on the ground. WLS announcer Herb Morrison and engineer Charles Nehlsen were making a disc recording and thus were able to capture the event "live" as it happened. This recording was so unique and dramatic that NBC decided to break its own rule banning records on the radio and allowed this recording to be broadcast on the network.

     For about 15 years WLS shared it's frequency with WENR as part of the NBC Blue Network. In 1941 WLS changed frequency from 870 to 890 kilocycles with 50 kw of power. The transmitter site was in Chicago's south suburb of Crete, Illinois from 1924 to 1938. In 1938, they moved to it's current location in Tinley Park.

The Top 40 era.....

     On May 2, 1960, WLS Radio changed  from it's 36 year farm and country format. With the  growth of Pop music since 1955, WLS targeted a new and younger audience. Program Director Sam Holman and station owners made the decision to change to a contemporary top 40 station. Announcers Dick Biondi, Art Roberts, Mort Crowley, Clark Weber, Bob Hale, Ron Riley, Bernie Allen and Gene Taylor brought a fresh, bright new sound to the Chicago airwaves.

By 1969, WLS was making it's transition towards the 1970's with a new slogan.."Musicradio 89" and a new Dj lineup,except for Art Roberts who left in 1971.


The 1970's...

     Music artists created so many changes in this decade on radio. From the bubblegum artists like The Osmonds, Bobby Sherman, Jackson 5, Blue Suede,Three Dog Night, The Carpenters to Rockers like Boston, BTO, Eric Clapton, The Who, Pink Floyd, Supertramp and STYX. The WLS Music radio playlist contained a big variety of hit songs. Mike McCormick was Program Director until 1973. General Manager Paul Abrams was Station Manager in the early to mid 1970's. That's when WCFL finally briefly won the rating war with WLS that went on since 1967.

The end of an era...
