Heroes webisodes (originally on nbc.com)
Wikipedia

There were several miniseries of webisodes during the run of Heroes, and I probably saw most (possibly all) of them, but I don't remember anything specific about any of them. Anyway, you can't find any of them on NBC.com anymore, but you should be able to find them on YouTube or something. Maybe I'll get around to rewatching them someday so I can write proper reviews, but for now I just wanted to mention that they existed.
