My order of preference from top to bottom:
Internet - this pretty much combines everything from the below 5. If I want to watch something, I can go on YouTube. YouTube or various sites for music, news websites or Wikipedia for reading, same thing for games. There's also the added benefits of being able to keep in touch with people with whom communication would be impossible otherwise, checking my credit card statements, and being able to find information on just about anything.
Radio - I like to listen to the radio, but only for the announcers. I don't care much for most of the music that I hear on radio (I prefer my own music). Also, I intend on getting a career as a radio announcer, so it's important for me to know what announcers are saying, how they say it, etc. so I can follow their example.
Games - For me, there are few hobbies that engage my mind like gaming does, while allowing me to take a rest from working out. Dodging lasers and explosions and stuff is always fun, as is cleaving giant robots in half with glowing green swords.
Music - I find myself using my MP3 player less and less nowadays. Then again, I almost always use it when I go running, which is fairly often.
Cable - Aside from the occasional episode of Futurama, or The Ultimate Fighter, I pretty much never watch TV anymore.
Books - There's a few books that I really like, but once you've read them once or twice, there's not much point in reading them again. For the amount of reading I do on the internet, I don't often read novels.
