"Google is experimenting with a search results box that inserts major brands atop regular search results for product-related queries.
They're not ads, and they're not regular search results. Search Engine Land spotted the branded results, which I was able to reproduce for several queries including 'digital cameras,' 'notebook PCs,' 'cars,' and 'mobile phones.' In each case, the first line below the ads atop the search results page contains the text 'Brands for mobile phones' and hyperlinks over a company's name to another search results page that combines the original search and the brand."
