I found this in an old copy of Broadcasting magazine, from 1947. There were a lot of ads like this at the time:
At the time, both these stations were owned by John Toole Griffin and family, who also owned Griffin Grocery Company in Muskogee. Both those sets of call letters have migrated a bit, KOMA across the dial to the FM band, and KTUL to a Tulsa television station.
And in the 1960s, both stations were local Top 40 powerhouses, something that couldn’t even have been imagined in 1947. (KTUL had already transformed into KELI.) The Griffins own a cluster of stations in Tulsa, but not this one, which was acquired by Clear Channel Communications, later rebranded as iHeartRadio. KTBZ, the current call (1430 The Buzz) has run some sort of sports format for two decades, and has gotten a daytime power boost to 25 kw. KOKC, still a corporate sister to KOMA, runs news/talk on its 50 kw blowtorch, owned by Tyler Media, based right here in the 405. (Come to think of it, when the current telephone area-code system went into effect in the late 1940s, the whole state was “the 405.”
