KDAL sells the Duluth-Superior-Iron Range market

KDAL 610 AM is a commercial talk radio station in Duluth, owned and operated by Midwest Communications. There was also a KDAL-TV, which later became KDLH and then merged with KBJR.

According to Wikipedia, KDAL signed on the air as a 100-watt radio station at 1500 kilocycles on Nov. 22, 1936. The KDAL call sign came from the founder’s name, Dalton A. LeMasurier, who was president and general manager of the station for many years.

The television station began broadcasting on March 14, 1954. The LeMasurier family sold the radio and television station in 1960. Following another sale in 1979, the call letters changed to KDLH-TV.

What is most interesting to me, in the adverts, is the way the Duluth-Superior-Iron Range market is described. At the time it was one of the 100 biggest markets in the United States, with many vibrant industries.

These ads are from Broadcasting and Sponsor magazines, found online in the Media History Digital Library.

Fascinating! Kudos to you for assembling this for our entertainment and education. I wish that I knew of all these resources and promotional adverts back in the 1980s when I researched and mapped the circulation and market penetration of the Duluth News Tribune and Minneapolis Star and Tribune for an economic geography course as a UMD undergrad.
