When last we saw "Community" nearly a year ago, Greendale Community College had narrowly missed being sold to Subway, the sandwich people. Typically, it was a metaphor for the show itself, which had struggled to survive throughout the years; "Save Greendale!" was the fifth season's hashtaggy theme.
Also, the show was then on NBC, a television network. It returns to the world this week via Yahoo Screen, which is something you need the Internet to watch.
