Believe it or not, but media.net works better for me on my main site than adsense (been using adsense for 4 years now).
I was certain that nothing can beat adsense. Well, I was wrong. For my website at least. Maybe you have a different experience.
But in my case it was like this. I had adsense installed on my site (wordpress). Had 3 banners in place. 1 on top (under article title), 1 in the middle of content (article body) and 1 in the sidebar (widget). The first banner under article title generates 75+% of all revenue. The banner in the middle generated only about 10% so I decided to switch it to media.net ads (actually media.net contacted me first and asked me if I want to try their platform). And now the funny part. One media.net banner overtook my main adsense banner. This media.net banner alone made more than the other 2 adsense units that are in place.
But like mentioned above already - yes, 85% of my traffic comes from USA, UK, CAN, .... It's quality traffic and converts very well. My site was also eligible for "premium media.net ads" which pay more.
So, media.net ads is what I run now in conjunction with adsense. I am sorry I did not made that shift earlier.
I have doubled my earnings this way. And no, my site is not earnings peanuts, it's earning 4 figures in € per month and now it's earning double those 4 figures.
I heard Media.net and Amazon are the best replacements but Media.net will pay you half of what Adsense does.

This is not true. Here's a direct information from my account manager at media.net:
"We start off with a rev share percentage of 70%. Later, our system dynamically changes the rev share based on the quality of traffic we receive - better the quality, higher the percentage. "
As a final note - stay away from infolinks. They're s**t. Amazon also doesn't convert well, unless you have a review website.
