The debut of Thrones' final season marked the largest night of streaming activity in HBO's history, and that means great things for the service's other series.

Barry, a tense dramedy starring Saturday Night Livealum Bill Hader, followed Thronesand saw its best night ever with 2.2 million viewers.

Similarly, HBO's long-running comedy VEEP, which followed Barry, experienced its best night since June 2016 with 1.5 million viewers.

And then Last Week Tonight with John Oliver, which followed VEEP(which followed Barry, which followed Thrones),championed its best night since August 2016, bringing in an audience of 1.7 million.
