Did anyone ever wonder how such a small independent TV channel was able to afford the royalties for Looney Tunes?
The same way they were able to afford "The Beverly Hillbillies," "Mr. Ed," and whatever other "old reruns" George was complaining about.....through the magic of syndication, which is no doubt one of the "fixed expensives" that Bob mentioned.
Before there was a Kids WB or a Disney Afternoon, weekday afternoon cartoons were syndicated to individual television stations. Companies such as Warner Bros., Turner, Universal, etc. would simply send a station a batch of loose cartoons to air however the station pleased....so it wouldn't be unusual to see a Popeye cartoon followed by a Bugs Bunny cartoon followed by a Pink Panther cartoon.
Warner Bros. ended their syndication offering of the individual cartoons in 1990 in order to compile a series called "Merrie Melodies." So feasibly, it wouldn't be impossible for U62 to have a selection of Looney Tunes shorts on hand.
But even then, I do see your point. U62 seemed more like a low-watt station that would air local high school basketball in prime time as opposed to a normal metropolitan independent UHF station.
