CHR today includes r&b, hip hop, dance, alternative, rock, pop, etc. It

as much variety as the format had in 1957... maybe more.


What about jazz? Country? MOR?

Since Top 40 was invented (August of 1952) to today, the format has
reflected mass tastes... principally 18 to about 34 year olds (the format
was "invented" by watching a 30-something waitress playing the same songs
over and over on a jukebox). Other than crossovers, there have been few
country or jazz Top 40 hits. And, while Top 40 was AOR in the early 50's
(Gogi Grant, Perry Como, etc..) it dropped the MOR tunes almost entirely by
the late 50's to early 60's... and MOR itself morphed into AC, and today
there are many, many AC and CHR crossovers.
