When my favorite TV station would sign on in the morning, they would have a "good morning" announcement and then show the test pattern with some music for 15 minutes before the first show came on. The last thing the announcer said before fading to the test pattern was something about "the best in entertainment". So I thought the test pattern was "entertainment".
A childhood belief about tv

others believed things like this
- everybody else were robots and I was a human test!
— Chas - I used to believe that whenever I got an F on a test it stood for fantastic. — megan
- If you pick Dandelions then you wet your pants. Honestly...I've never tried and I'm not going to test it!— Charlene
- I used to think that 'black comedy' was show like Family Matters and The Cosby Show.— Katie
- I used to think that every time a show came on tv, that the actors were inside my tv acting out the show.Anon
- i thought there was a "that 80's show" and "that 90's show" too— :D
