Google seems to be testing a new interface for their search results.
Instead of showing the URL of the page, Google is showing the name of the site. They've done this before, in 2011 but never above the title of the search result. They've only done it in place of the URL location, but not above the title of the search result.

I don't like it, any of it. I dislike not showing the whole URL and I dislike showing the URL above the title of the page.
