NBC will debut the season/series premieres of some of its lineup on the online streaming service Hulu one week before they air on the broadcast network. For example, the series premiere of the new Knight Rider and the season premiere of Lipstick Jungle, which will first air on NBC on 9/24 will be available on Hulu on Wednesday September 17.
Also available first online will be Chuck, and Life which will be available on Hulu on September 22, but don't debut on NBC until September 29.
This is not however being extended to every show on the peacock network. Shows that traditionally have performed well on television will make their season's bows on the TV network first, and then show up on Hulu a day later as is the case with Heroes, The Office and My Name is Earl.
Even some new shows like the My Own Worst Enemy will bow first on the network on October 17 and be available on Hulu the next day. Crusoe, which premieres on NBC on Friday October 17, will show up on Hulu on Monday October 20.
But good old 30 Rock, which doesn't have its season premiere on NBC until October 30, will appear first, a week earlier on Hulu.
You can see the full Hulu schedule via Hulu's Fall Premiere Lineup. Note the Hulu lineup also will display shows from Fox and some from USA, but they give you a week by week schedule of when the premieres will show up on Hulu.
Update: Separately, Variety is reporting that awareness of Knight Rider and CW's 90210 is high in advance of the premieres. Variety notes that awareness was higher for Knight Rider than even 90210, but that the other new fall shows have little awareness among TV viewers.
