MSN Adcenter is Microsoft’s flagship search advertising product which is similar to Google Adwords. It too, is a PPC engine where you are only charged for actual clicks as opposed to paying a certain rate for your advertising.
MSN Adcenter also has a search network and content network, although the content network on MSN is vastly smaller than Google’s.
MSN Search Network
The text ads for MSN’s search network appear on both the Yahoo and Bing search engines, to the top and right of the natural listings. Here’s a screenshot in Bing:

MSN Content Network
As mentioned above, the MSN Content Network is much smaller than Google’s – one key difference is that MSN does not allow image ads (ie banners) in their content network; just text ads. Here’s a screenshot showing where they appear on MSN Money.
