The Most Popular Radio Format for Millennials?

From Tom Taylor's NOW column...

For the 65.2 million Millennials, “country is now the #1 format". That shift completely rearranged the usual order of things for 18-34s, with country (at a 16.5 share of listening) dethroning Pop CHR (13.5). Rhythmic CHR is #3 with that demo at a 6.7 share, closely followed by AC at 6.5 and hot AC at 5.8.

That's definitely a first for country music radio.
