Google Search Tests Suggested Channels Box

Google seems to be checking a brand-new feature in the Google search engine result called “recommended channel.” I personally can not replicate this but he is a screen shot from Jonas Sickler on Twitter who spotted this last week. I dont think Ive seen this before and it just appears like an unusual title for this kind of query and the search results that Google lists.Any ideas what this is exactly?Forum discussion at Twitter.
