Time.com has a long article about how Lost and its fans has changed television. The article is bit long but it’s still a nice read.
The mystery of Lost–and the opportunities for cyberanalysis–turned it into TV for the post-TV generation. Besides stoking interest, technology has affected the kind of storytelling Lost can do. On a practical level, DVRs, DVDs and iTunes downloads mean it’s less likely fans will miss episodes, fall behind and give up, which allows the writers to keep the show complex and challenging. “A show that is as serialized as Lost would have had a much harder time pre-iPod, pre-DVD, pre-streaming video,” says Abrams.
EDIT 9/25 (by Cecilia): Believe it or not, I was actually interviewed for this article. I was contacted through a friend, as a moderator of another site, and was on the phone with one of the writers for about 30 minutes. I was very excited about getting in the article, but unfortunately they dropped me my comments. :( They did ask a lot of questions about what I thought about the direction of the show, and what made it unique. However, a friend and co-mod (Craig) got a quote in in the last paragraph, happy for him!
