Which advertiser programs?


Just wondering if someone could provide information   on ad networks that 

display ads that mask page content.

If i have a page of information that is important for some people and i’m distributing it for free… what are the ways i could monetise it through advertisement…

for example: Advertisements that mask the page contnet and need to be manually closed before the user can read the conetent.

So because the ad got displayed and the user had to manually close it it should make some money for me… right?

What kind of Ad networks are these? Does google also provide such ads? Which are the best ad networks for such ads out there?

Any other way i could monetise this information which i’m otherwise offering free to potential users.

All hints and answers are much appeciated.
