Inspired by a conversation with @lucas. I'm sure there were many more, but these are the ones I remember.
  1. Space Camp
    Static
    This requires no explanation.
  2. Zenith TV/VCR Combo
    Static
    As a kid, the *dream* was your own TV. I wouldn't be surprised to learn that Nickelodeon Studios was Zenith's #1 customer.
  3. Huffy Bike
    Static
    This is a controversial third pick, I know, but if the bike had pegs so you could do some sweet jibs then this definitely deserves the #3 spot.
  4. Casio Keyboard, Guitar, or Saxophone thing
    Static
    A little nerdy, but even as a kid I knew there was something sort of cool and funky about Casio. Sorry, Yamaha.
  5. Toys R Us Gift Cards
    Static
    This would rank higher if the network didn't have a dedicated program to watching kids race through Toys R Us, stuffing their carts with whatever they could in the allotted time frame. Kind of makes a gift card seem lame...
  6. Sketchers "It's the S" shoes
    Static
    Oh cool, shoes...
  7. Tiger Electronics' Games
    Static
    How dumb do you think I am??? Nintendo or Sega or GTFO.
  8. Sand art
    Static
    Sand is not a prize. Sand is something you can walk outside and literally pick up off the ground.
