Also, back during B94.5 days country was not as popular as it is today.
I'm not quite sure if that statement is true. If you remember, there was that period from about 1991 to about 1995 when Country was red hot. There were a bunch of new artist that had come along and shook up the format and brought in new Country listeners. Brooks & Dunn, Garth Brooks, Tim McGraw, Toby Keith, John Michael Montgomery, Wynonna (as a solo artist), Martina Mc Bride, Little Texas and Patty Loveless were some of the artist who brought new excitement to the format, just as Lady A, The Band Perry, Thompson Square, Zac Brown, or Taylor Swift do today.
The only hard numbers I can give you are from the Orlando 3 county metro. When you add all of the shares of County today, you get about 7 shares of County listeners (in March there was only 5.2), in a population of 1.5 M. In B94.5 era, when the population was just under a million, you could at times have 17 to 18 shares of County. As Just Me mentioned, I don't know about nationally, but in Orlando, Country was more popular back in that era.
