I have to assume that the block you're referring to is paid advertising. It's the one at the upper-right part of the home page? At the moment on my computer, it's clearly an ad for Kenmore.

At the bottom of the home page is a block called "Featured Reviews." For the past week or so (ever since the new page was rolled out), that's been the same three air conditioner reviews: Kenmore, DeLonghi and Haier. It must be nice to have a review so consistently featured on the home page...
