NBC's broadcast of "The Wiz" in December marked the third year in a row that the network aired a live performance of a musical on national television. But if things hadn't gone well, it could have well been the company's last attempt to turn the event into an annual holiday tradition. Poor reception and low viewership for 2014's "Peter Pan" meant that the pressure was on to make "The Wiz" a hit—or to wave goodbye to live musicals for good. Luckily for NBC, "The Wiz" impressed, bringing in 11.5 million viewers and ranking high in the ever-important 18-49 age group. It also set records for its traction on social media. NBC's exploration of live, scripted performances has also resulted in the groundbreaking sitcom series "Undateable," which has been broadcasting its third season live each week, with two performances a night—one for the East Coast and one for the West. The show received lackluster reviews in its first two seasons, but the live aspect of season three has injected it with fresh life—not to mention plenty of opportunities to incorporate social media directly into the show.
