Most often if you find a site that looks for community interest (IGN.com is an example), then it's a great way to get an "in" with the company. You could start off writing something you're passionate about that the community is interested in for a website, then perhaps someone will notice you or you'll be able to join a media company (like the parent company to tomshardware for example), and then you're set! Note that this might take a while though, as your mileage may vary.
