We like to imagine that one day you'll be able to find pretty much any movie or TV show ever made online -- without resorting to BitTorrent. HBO is bringing us a bit closer to that day by rolling out a new broadband video service to Wisconsin cable subscribers, with a wider rollout scheduled for later this year.

HBO Broadband is free for existing HBO subscribers, and as far as we can tell, it's unavailable to non-subscribers at the moment. While most broadcast networks are making some content available for free on the web, HBO's service requires a PC application. No Mac, Linux, or portable version is available yet. Shows will be watchable for up to 4 weeks after you download them, after which point we assume they explode. You know, or just won't play anymore.

Content will vary from month to month, and each month HBO will make every single episode of one original series available. This month the service is offering some episodes of popular shows like The Wire, Sex and the City, Curb Your Enthusiasm, Deadwood, and Flight of the Conchords.
