After seeing cable companies fail to get into the internet, I'm convinced companies try to stop progress instead of embracing it. They don't see progress as an opportunity, but rather as a threat. They don't realize how much they are hurting themselves.
I read an interesting article on here about the rise of the cell phone camera, the amount of R&D into it compared to traditional cameras, and how slowly traditional camera manufacturers have progressed. Sure, cell phones have to overcome a smaller sensor... but traditional camera sales have been obliterated.
