As mentioned before, some of the Networks are releasing a few TV Premier Pilots for download. There are also rumors that some networks leaked many premiers out on torrents earlier this Summer to create buzz.
To add to that, NBC is now offering free downloads of their popular shows via a new service they call NBC Direct. Shows such as The Office, 30 Rock, and Heroes will be available to download to your desktop using the NBC Direct software. The initial beta launch will provide users with a free subscription option allowing the viewer to pre-select their NBC shows and then those shows will auto-download to their computer once available (after the broadcast). DRM will be included on the downloads so the software will allow users to view each episode for up to one week before the shows "expire". Unfortunately there will be advertising included, but hey - it's certainly a step in the right direction. I'm beginning to think NBC understands their TV world is shifting towards the internet and toward TV watching flexibility due to Tivo's DVR's and Home Theater PC's.
UPDATE: Digital Alchemy reports this very useful addition to the story:
"However, if you're impatient for legal TV downloads and you have an Intel Centrino or Viiv-based PC, you can get VIP access to NBC show downloads right now."
Here's a list of the shows that will be available for download from the new NBC Direct Service
