 More often than not, the few people who could watch WKNA-TV had to do so by buying an expensive converter, and even then picture quality was mediocre at best.Local and national advertising were almost nonexistent, as no advertiser wanted to buy time on a station where he couldn't even see his own ad.With limited revenue, WKNA-TV's on-air look was very primitive even by 1950s small-market standards.
