Julianne Hough isn't the only one who will be working up a sweat Sunday night. "Grease: Live!" is expected to generate millions of tweets, perhaps even as much as TV's most hypnotic dramas receive. But anything short of a rush for T-Birds jackets on Amazon will pale in comparison to next weekend's Super Bowl. The number of live tweets worldwide during premiere broadcasts:
2014 FIFA semifinal, Germany vs. Brazil: 35.6 million
Super Bowl XLIX (2015): 28.4 million
2015 Grammy Awards: 13.4 million
"Empire" season finale, March 2015: 2.4 million
"The Wiz Live!" 1.6 million
"Scandal" (average episode): 559,000
