TULSA — On December 31st, 1949, KRMG radio began broadcasting at 740 kHz on the AM band in Tulsa, Oklahoma.

It is the only radio station that has remained on the air every day since, and one of the few that has never switched call letters or that original broadcast frequency.

There have  been many changes over the years, certainly, as the station changed with the times.

All this year, the station will celebrate the milestone, and begin counting down to its 75th anniversary.
