The Star Wars toy phenomenon began in 1978 with the original action figures, toy light sabers and blasters, 12-inch figures, toy vehicles, and much more products. These toys are known as the vintage Star Wars toys. A lot of them were made by Kenner.
Today many of these "vintage" figures are quite rare and hard to find. Many are also worth a lot of money. Recently, a toy line called Star Wars: The Original Trilogy Collection, brought back elements of the original vintage toy line, such as vintage packaging. With the coming of Star Wars: Episode I, Lego began creating little (and quite large) buildable Star Wars characters and scenes. Recently, the Lego creators have invented light-up lightsabers for their figures. Lego even made a video game.
Star Wars toys commercials from the 1980's:
Many types of toys have been made. Darth Vader helmets and voice changers now inhabit the shelves, usually right next to the Ultimate Lightsaber Kit, which contains parts to design and assemble your own functional lightsaber toy. The term "Expanded Universe" was first used with Kenner's assortments of action figures based on the various Star Wars novels, comic books, and video games. Previous toys based on novels were sold by Galoob as "Epic Collections."
