7 businesses Amazon wants to shake up

Amazon already offers a vast array of movies and television shows for streaming on its Kindle Fire tablets. Now, the company wants to take over the TV itself, unveiling its Fire TV set-top box last week that enables television sets to access Internet programming, video games and streaming content from its Amazon Instant Video service. The device puts Amazon in competition not just with Google (GOOG) and Apple (AAPL), which also offer streaming media gadgets, but with offerings from cable and satellite companies and Netflix (NFLX), which currently sit in most living rooms.
