A couple years ago I was watching Hulu and noticed the ads always felt like they took much longer to play than they should.

I got out my iPhone and timed the seconds as they counted down during ad time on Hulu. Each second of ad time on Hulu took 1.34 seconds of actual time to pass. They were telling you for example, that there were 2 minutes of ads about to play, but the 120 second countdown would actually take 160 seconds to pass.

I stopped watching Hulu altogether after that discovery. I think I checked back in more recently and they had stopped doing that, but it's still a little telling about where their head is at regarding ads and their customers.
