I'm not a big fan of pre-roll, I would recommend doing your own research by googling the pros and cons of pre-roll.
The fact that pro-roll is hated by a small percentage of end users and somewhat still effective does't go well with are strategic digital marketing strategies.
Not a small percentage hates it, I think everyone hates it!, but to Paul Ray's point--it is what it is.
I've learned to live with it.
But I'm interested on knowing why you think pre-roll doesn't go well with other digital marketing strategies.
