The series returned Thursday night to 8.4 million viewers.
That makes it MTV’s most-watched series telecast of all time. (For EW’s recap of last night’s shenanigans, click here.) In MTV’s 12-34 demo, Shore was up 63 percent from season 2′s opener. Even more impressive: Shore had a 4.2 adult demo rating — that’s higher any show on the big broadcast networks last night except chart-toppers The Big Bang Theory and Grey’s Anatomy (which Shore tied).
