writes "The Comcast/NBC-owned Syfy cable channel has decided to delay Online airing of new episodes. Most of its shows (including Haven, Ghost Hunters, Sanctuary) will not be legally available online for 30 days, in an attempt to get more people watching the show live on their Cable or Dish TV subscriptions. The response from Syfy VP Craig Engler: "How soon we post video is dependent on various agreements with producers, distributors, etc. We post as much as we can as soon as we can."
The explanation given by Hulu on their Stargate Universe page: "The first 3 episodes of the new season will be available the day after their original airdates. Subsequent episodes will become available 30 days after their original airdates.""Link to Original Source
