What is your earning with these ads network?

Hi,
well im new here...
when im searching around the G, visited on certain website, i found some ads network like
mgid, spoutable, revcontent and etc...

Tested with adsense and some CB products but still no penny going to account.

So, anyone have some experience with that ads network? mgid spoutable etc?
