Just got free tickets in the mail to watch some TV shows at an airport hotel a week from now, and give feedback “to directly influence what you see on television in the future.” Learned from Wiki, however, that it’s a scam for advertisers: Television Preview - Wikipedia
Went to one with my family years ago. We saw two bad sitcom pilots (one about a couple struggling with their jobs being in different cities the other starring Sally Kellerman). We filled out a survey of grocery products we might like to try with the promise that one person would win those products. I won, but instead I just got a check for the value of the groceries. So instead of getting the new flavor of Pop Tarts I wanted my mom just bought real food.
