MyAds announcement:

In an effort to maintain a position of transparency with all of our advertisers, we are alerting you to a change that will have a direct impact on the existing campaigns in the MyAds system. Effective Wednesday, January 12th, 2011, we’re removing MySpace as its own separate channel within MyAds and merging it with the Social Media channel.

The Social Media channel delivered far better CTR for me so I'm not very happy about the change.
