adsense

it turns out that adsense supports text, image, and video ads -- based on content. according to wikipedia:

Many sites use AdSense to monetize their content and some webmasters work hard to maximize their own AdSense income. They do this in three ways:

1. They use a wide range of traffic generating techniques including but not limited to online advertising.
2. They build valuable content on their sites which attracts AdSense ads which pay out the most when they get clicked.
3. They use copy on their websites that encourage clicks on ads. Note that Google prohibits people from using phrases like "Click on my AdSense ads" to increase click rates. Phrases accepted are "Sponsored Links" and "Advertisements".
