Summer turned out to be the place to launch for midseason NBC series. Multi-camera comedy Undateable has been picked up for a 10-episode second season, following a similar renewal for drama The Night Shift. Both found a way to transform themselves from summer burn-offs to solid performers to returning series. Airing back-to-back originals, Undateable premiered with a 1.3 rating in adults 18-49, almost doubling the debut of NBC’s 2013  comedy series Save Me to post the highest-rated summer comedy premiere on the Big 4 networks in five years (since ABC’s toon The Goode Family on 5/27/2009). It even edged one of NBC’s fall Thursday comedy debuts, Welcome To The Family (1.2 on 10/2/13). Undateable‘s numbers slipped but largely stayed above the original broadcast comedies that aired last summer and kept clear of the lows posted by several NBC fall comedies last season, like The Michael J. Fox Show, Sean Saves The World and Welcome To The Family. Undateable, whose first season consisted of 13 episodes, also regularly topped Fox drama Gang Related. “Overexcited to do 2nd season of Undateable on NBC,” executive producer Bill Lawrence tweeted tonight. The renewal of Undateable, from Warner Bros. TV and Lawrence’s Doozer, bodes well for NBC’s midseason entry One Big Happy which was going to be the single multi-camera comedy on the network’s schedule next season. Created by Adam Sztykiel based on the book by Ellen Rakieten and Anne Coyle, Undateable stars Chris D’Elia as a carefree single thirtysomething who befriends a group of “undateable” guys.  Sztykiel, Lawrence and Jeff Ingold executive produce. The renewal keeps Briga Heelan as one of the busiest comedy actresses. She co-stars on Undateable in addition to her starring role on Lawrence’s TBS comedy Ground Floor, which also was renewed for a second season.
