MSN Messenger has included a Search bar function enabling users to search information whwnever they write on their msn messenger.

MSN Messenger used to have small banners on the bottom of each msn buddie but now it has a picture banner that leads you to msn Live search sponsored links.

I do not know how much conversion advertisers can expect from this sponsored links model or any other add your link submission.

Place: Msn Messenger
Banner: Picture banner
Leads: Leading users to MSN Live Search full of sponsored textual links for many and not one exclusive advertiser.
