Lol I'm still watching this thread.
Hmm.. I notice I skip channel trailers if its just a random video. If its a real channel trailer, I could sit and watch it for less than 40 seconds. If its more than 40 seconds I usually pause and browse the channel.
I mean by 15-30 seconds in, I could already get a sense on how people edit and such, so I would start looking around instead. But if its a reaaalllyyy good trailer, I could watch at most 1 minute plus, no more than 2 minutes tho. By 1 minute plus, I'd want to watch a real video, not a trailer. >.>
I kept track on my trailer watching behaviour because of this thread lol.
