How are the weekly/monthly/yearly countdowns computed?
From November, 1975 through December, 2007, the syndicated Dr. Demento Show had a weekly Funny Five countdown of “the hottest and the coolest” songs of the week. This was based on phone, mail, and internet requests, as well as timeliness, album sales, and Billboard charts. Starting in January, 2008, this was changed to a monthly Top Ten countdown. It is still calculated basically the same way as the Funny Five. The syndicated show had previously featured a weekly Top Ten from September, 1974 through November, 1975. The countdown on the live KMET show started as a regular feature in 1972 when it was a monthly top five. This lasted through September, 1972. Starting September 17, 1972, this became a biweekly top five, which lasted through February, 1973. On March 11, 1973, this became the Top Ten, and on March 25, 1973, became a weekly instead of biweekly feature. The KMET Top Ten lasted through May, 1983, after which the Funny Five was heard weekly on KMET and subsequent Los Angeles radi
