AC stations touch the 70's music. I have not come across any Hot/Modern AC station that touch 70's music. It's typically 80's, 90's & Today, though some stations dropped 80's music. This format from my listening experience focuses mostly on 90's music with a mix of 80's, and music released in this decade up to new music. Depending on the Jack or Jack clones, they'll mix 60's tunes into their playlist. As for Jeremy's comment up above about WNND & WTMX. The reason WNND tanked is because WTMX & WNND (now WILV) are sister stations, with similar formats. One had a narrow playlist so it didn't cause ratings to drop on the top billing Hot/Modern AC station. When Bonneville sold the Loop, they couldn't keep WNND a flanker. That's why they dropped the 80's & 90's format. If WNND were run by a different company, it would have put some competition on WTMX like it did in the 90's when it was WPNT. In the next decade, Hot AC will drop 80's music and be 90's, 00's, and Today. I remember Hot AC in the 90's being 70's, 80's & Today, which was the case with the old WPNT in Chicago.
