The pay-per-view television concept Alfred Hitchcock jokes about in his opening monologue was actually conceived and tested about a decade before in the early 1950s. Homeowners had devices installed that allowed them to put coins in an aftermarket device attached to their television which granted them access to special programming. This was resisted by movie studios and advertisers and did not get past the experimental beta testing phase until cable television made it more profitable in the 1980s.
In his opening monologue, Alfred Hitchcock has booths behind him that are similar to phone booths, but he claims house televisions that people can sit in and watch for ten cents for three minutes of "television". A thirty minute television show would cost a dollar (equivalent to $8.62 in the year 2021). A primitive "pay-per-view" television concept.
Alfred Hitchcock jokes that a man left home with fifty dollars in dimes and put them all in the pay television booth. At three minutes of viewing for each ten cent deposit, that fifty dollars would buy 25 hours of television viewing.
