The pilot episode has been available for download for 33 hours. In that time over 5300 people have downloaded the show and the buzz is buzzing harder than ever. While this is a good thing with regards to generating more interest for the series, NBC probably isn't too happy about missing out on ad revenue. Then again, it might be NBC who leaked it in the first place.

The bit torrent download can be found at http://www.eztvefnet.org/. Simply do a search on "HEROES".
