Microsoft has rebranded their search ad service from Microsoft adCenter to Bing Ads. Part of that, they are naming the Yahoo / Microsoft Search Alliance as the "Yahoo! Bing Network."
The new quick way to login to your adCenter, I mean, Bing Ads console is to go to bingads.com.
Microsoft said it is not just a cosmetic change, that they also made several changes in the past couple months. Well, those changes were made under the adCenter brand, so really, it does seem like just a rebranding thing.
Personally, I like Bing Ads much better than adCenter. So good move.
Bing Ads has a Facebook page and Twitter profile. I believe Twitter and Facebook migrated followers and fans for them, but I can be wrong.

until they go worldwide for publishers, they don't have a chance against Google...
