Ah, cartoons!... People loved 'em!... In the 1960's and mid-1970's they were STILL part of EVERY showing: cartoon first, short (if any, depending on feature length), local screen ads (if any, never more than 3 brief on 35mm sound film), one or two coming attraction trailers (NEVER more than two), the feature... Then, the cartoon (only) was repeated AFTER the feature!... Probably 90% of the audience (mostly adults) stayed for the cartoon repeat!... Of course, these were 20 minute reels with the pre-show stuff all spliced in ahead of the feature, and you could run part of the reel, stop it, de-thread, and hand rewind what had been shown, for the next showing... Often, the pre-show stuff was enough to make up a shorter reel to run before the feature...
In the 1960's cartoons cost a flat $2, or $2.50 each (depending on the distributor) for a week's playtime, and if shipped with a feature, there was NO additional charge... By the mid-1970's the cost had risen to $10 for most, and the prints were usually in sad shape, as most were the original prints from the 1950's and had a million miles on 'em... No one had made any NEW cartoons since the late 1950's and despite the huge catalogue of titles, we were repeating playdates... The (then new) Saturday morning cartoon shows on TV soon exhausted the backlog, so we were playing the same ones, and theaters lost still another EXCLUSIVE... Disney would, perhaps every couple of years, attach a new especially made cartoon to the head of one of their features, but other than that, we were paying upwards of $10 to $25 for playdates of old battered cartoon prints that were being show on free TV every Saturday morning!... AND the more extensive end credits which were becoming more commonplace, virtually eliminated repeating the cartoon for the small handfull of customers who would sit through 5 minutes of scrolldown to see the cartoon again...
By the mid-late 1970's I reluctantly did away with cartoons as part of the program, and another sad chapter closed on what was ONCE the most fun-oriented business you could participate in!... SAD, SAD, SAD...
