If the executives are making business decisions based on only what they like or know, then they should be demoted to the mail room or something. The first lesson of marketing is to find out what people want and provide it -- even if you don't like it yourself or never even heard of it. They must be doing some kind of market research (at least, I hope they are!) and the results probably don't inspire them to release too many shows from the 1950s or 1960s. I don't really expect them to. But I do wish they'd license them out.
