Another industry to go: DVD Rentals - Eclipsed by Streaming
Redbox is doing pretty well, actually. People seem OK spending a buck or two occasionally to see a specific movie.
Cable TV, on the other hand, is losing customers right and left due to streaming video. As more video is availabel via the internet (and even grandma finally figures out how to hook a computer to a TV), those $50-$100 a month cable bills start to look pretty steep.
