The first episode is about the Star Wars toys and memorabilia, which have made more money than the actual films in theaters. It was really interesting to see how, when George Lucas was making his first Star Wars film, it was next to impossible to get any toy company to take a gamble on him. All of the big name companies like Mattel and Hasbro turned Lucas down and he was forced to use a small virtually unknown toy company called Kenner. Kenner agreed to take on making the movie toys, but only if they retained 95% of the profits. Lucasfilm was desperate enough that they were forced to agree to these terms... and then of course, the movie was a bit of a hit. It would be years, though, before Lucas would be able to get a better deal.
After the movies became mega hits, they of course get more money to make bigger and better toys- like the model Millennium Falcon- but happily there are also a lot of really cheesy items, like the lightsaber toothpick holder.
