The boob tube
There's a neat website, TVparty!, promoting a book of the same name, which has several interesting behind-the-scenes and tribute articles about TV programs. Some interesting looking ones are about the unseen pilot episode of Rod Serling's The Twilight Zone, the two shows that Andy Griffith made in the early 1970s, and a tribute page about the Gorgeous Ladies Of Wrestling TV show of the 1980s.
Thanks to Kathy Shaidle for spotting it.
