I think every webmaster has an Adsense account. Well you can earn not only with your website, but being active in some big websites too that shares their income with the members. They have systems so the ad revenue can be shared between all active members.

These websites use Google AdSense to automatically serve relevant ads for the content on the page. Google pays (you) AdSense publishers on a per click basis as well as per impression.

Few months ago YouTube started paying high quality, original content uploaders through it revenue sharing program YouTube Partners.
