Google is yet again experimenting with the snippet display in the search results. Google Operating System noticed Google bringing back a test from 2011, where they replaced the URL in the snippets with the site name.

Earlier this year, Google also tested removing the URL section completely.
You can see more examples at Google Operating System, and this was first spotted by Techno-net.
