I read this today:
Variety (November 21, 1928) wrote: "Not the first animated cartoon to be synchronized with sound effects, but the first to attract favorable attention. This one represents a high order of cartoon ingenuity, cleverly combined with sound effects. The union brought forth laughs galore. Giggles came so fast at the Colony [Theater] they were stumbling over each other. It's a peach of a synchronization job all the way, bright, snappy, and fit the situation perfectly. Cartoonist, Walter Disney. With most of the animated cartoons qualifying as a pain in the neck, it's a signal tribute to this particular one. If the same combination of talent can turn out a series as good as Steamboat Willie they should find a wide market if the interchangeability angle does not interfere. Recommended unreservedly for all wired houses."
It almost sounds as if they are recommending the 1928 cartoon "Steamboat Willie" to all households which are "wired", painting a picture in my mind of television cables going into early television sets in their homes. But the late 1920s seems far too early for that. Maybe they are talking about some early, small-scale TV test market? Or was "houses" slang for "theatres"? But even if the latter is true, what do they mean by "wired"? Were the cartoons actually "wired" with cables? Surely they got film roll prints physically delivered?
