Question: When is the 8th season of American Dad going to premiere?
Answer: September 30, 2012 at 9:30 PM EDT/PDT on the Fox network.
With the exception of the 6th season that was delayed due to the MLB playoffs, Fox has traditionally premiered their new season of American Dad on the final Sunday of September. This tradition started with the 3rd season back in 2007.
If you're looking to catch up on the 7th season of American Dad, you can stream/download the season on Amazon.com.
