According to The Hollywood Reporter, Fallout viewership reached 794 million minutes on Prime Video for the week of December 15-21, which covers when Season 2 debuted on December 16. Season 1 racked up 2.9 billion minutes of streaming time during its own opening week in April 2024. That's a 72% decrease, but the massive downturn was no doubt attributable to how the two seasons were released.
