AMC’s sci-fi drama Humans clocked 2.5 million total viewers in Live+3 for its June 28 series premiere, up 43% from Live+Same Day.

In the key demos, it scored 1.2 million adults 25-54, up 50% from Live+SD, and 1.0 million adults 18-49, up 52% from L+SD, according to Nielsen stats.

As noted previously, the debut of Humans was just over 30% of what it got in the UK when the Sam Vincent and Jonathan Brackley-written series launched there on June 14. The first showing of the sci-fi show with Gemma Chan as synth Anita had just over 4 million viewers and was Channel 4’s best ever original drama debut. The second UK airing on June 21 averaged 2.5 million total viewers in what is a busy 9 PM Sunday slot.
