The premiere numbers were nearly double the season two debut night for Euphoria, which recorded 2.4M last January. That series went on to average 19.5M viewers per episode in the U.S.
HBO said that Sunday night viewership typically represents 20%-40% of the show’s total gross audience per episode.
The series, which is based on the PlayStation game, takes place 20 years after modern civilization has been destroyed. Joel, a hardened survivor, is hired to smuggle Ellie, a 14-year-old girl, out of an oppressive quarantine zone. What starts as a small job soon becomes a brutal journey as they both must traverse the US and depend on each other for survival.
