My colleague and I noticed a test version of this appear a few months ago:

The test version was more simple, and only had the box around the brand. Importantly it only showed 5 results on the first page below the brand term. As usual, the move will help push affiliates off the first page. Although undoubtedly, the brand term is the most relevant content, so it makes sense.
What does everyone else think of this?
