Candy and other obvious products.

Snickers has been around since 1930 and 72 years later they get the idea to try a second kind of nut, Reese's Peanut Butter Cups took about the same amount of time before they came up with a spin off product. These are not giant innovative leaps by any means, especially when you take into account that these are companies that pretty much exclusively make candy. Maybe it is just that people in the past didn't care about options, but that clearly isn't the case now with every kind of candy having a white chocolate version, a crunchy version, and dark chocolate version. There are even candies that Frankenstein 5 kinds of candy to quench those that can't even commit to a candy bar. When I see these candies stacked in the checkout lane I always think back to a trip I took the the GM car design studio that I went to when I was a little kid. They had cars designed out to 20+ years into the future. I looked at these cars that were meant for decades out and I thought those are the cars I want now, comparatively the lame little changes they had for the next year sucked. Even as a kid I thought that though the future design was great they were designing like cowards, acting like they would run out of ideas if they just through them out now. You can always think of something new. I know that there aren't a lot of ways you can configure nougat, carmel, chocolate, and nuts but 70 years is a bit to long to start to innovate.
