Forget Ryan Seacrest,Casey Kasem was "American Top 40"-No ifs ands or buts.

Casey Kasem Was And Still Is The King Of The Countdown.

While it's hard to believe today, the vast majority of stations that ran AT40, well into the late 1970s, were AM stations, not FM.

Casey Kasem RIP .

[@donmccullen1973]

Correct.

[@danacarlson1672]

Casey was to Top 40 radio what Michael Landon was to prime time television, Johnny Carson to late night television and Walter Cronkite to the news.
