That is the most watched HBO drama series premiere in the combined metric since the debut of True Detective almost three years ago, which also averaged 3.3 million multi-platform viewers. Westworld more than doubled the L+SD debut of Vinyl (1.4 million total across platforms).
The well reviewed AI drama, written/executive produced by Jonathan Nolan and Lisa Joy and executive produced by J.J. Abrams, also was strong on Twitter, surpassing any recent drama debut on HBO, including True Detective.
