Sign up for RewardTV. This is a cool site where you can answer questions about TV shows that you may watch throughout the week. Quizzes come up the day after a show airs. You can play about 6 games a day and earn points that can be used to redeem for Gift Cards and you are entered into sweepstakes through the site.
I signed up today after learning about it from my friend Autumn. It looks like the site has the purpose of gathering information about TV watching and advertisements because some questions about each TV show have questions about ads interspersed throughout the quiz. Each correct question gets you 100 points. There are also other surveys that you can take for extra points. So far it seems pretty fun.
