Wow. According to the news I read, along with the apparent lack of promotion on ABC and ABC.com, American Inventor brought in the viewers, being first in the ratings from 7-9 (CT). I guess I should have seen this coming if I heard others talking about it...
What was strange is that ABC never wholeheartedly promoted the series, thinking that this show was going to fail, providing minimal coverage on the ABC.com homepage, and a barebones official website. I'm sure that's gonna change now.
