Some days ago I found this email in my box, about an advertising service called NeverblueAds:
and I made some research about it, specially compared this NeverBlueAds vs Google Adsense,
PPC: NeverBlueAds vs Google Adsense = winner Adsense - there is no match, but neverblueads is not just an advertising network, they pay you for several affiliate services,
Referral: Make others register under your ID account, and neverblueads will pay you
Affiliate Marketing: Check this ebook, HERE
NeverBlueAds payout at: $25,00
Conclusion: If your destination is to make money most of all from a pay per click service, neverblueads is not the best choice, instead, if you're searching for a multi advertising service that is based on affiliate promotion, in that case neverblueads could be a nice experience.
