Tickle Me Elmo - 1996 - by Tyco - Only rivaled by the cabbage patch, Elmo was a pricey toy wasn't expected to be a hit, so supplies were limited. Elmo was featured on The Rosie O'Donnell Show and it took off. Dolls sold on black market for hundreds of dollars. Cartier even put one draped with a diamond necklace and bracelet in it's 5th Avenue store, advertising the doll was a free gift with the $1 million purchase. Elmo is still on the market, updated to the LOL Elmo for 2012.
