Webcast day and time survey results

Back in April, I wrote a post and linked to Ken Molay's survey about the best day and time for a webcast. He's published the results here. I think it's interesting how the West Coast wants morning events and the East Coast favored afternoon events. Ken suggests perhaps it's conditioning -- that's when they're used to seeing webcasts?

Applying the same logic, I wonder if West Coast TV viewers were asked about their viewing preferences for live events like sports playoff games, if they'd choose 6pm start times because that's what they're accustomed to? I'd love to see data on that. I'm sure the NFL has some sort of data that they use to justify such a late starting time for Monday Night Football games for East Coast viewers.
