Top Ad Networks to be in?
I pretty much quit the internet game for about 7 years and have recently started getting back into it. In the time I spent away, a lot of the ad networks I used to use have bit the dust (ie, Yahoo, Fastclick, Azoogleads). So what are the good ad networks these days? I'm currently only using Adsense, but I feel like there have got to be other ad networks worth looking at.
By the way, I am aware that there is a stickied thread for this topic, but it hasn't been updated in over 2 years.
