Muddiest Point for 10/25/10

I actually have a question about last weeks readings.  For the Google video that we watched, Larry page mentioned that Google does not accept money from company's to have their website put first on a search result's list.  He mentioned unlike some of our "competitors".  So my question is which search engines accept money to have certain people's websites put first?  I assume none of the large and legitimate engines like Yahoo or bing.  But do other medium sized engines do so, ie: msn.com?   I was just wondering because if they do then I don't think I would want to use them. Thanks.
