Paramount Plus’s Knuckles knocked Amazon Prime Video’s Fallout out of the top spot in TVision’s Power Score ranking of the top show on connected TV the week of April 29.

Fallout had been No. 1 for three weeks and drops to No. 2 behind the Sonic the Hedgehog spinoff.

Rounding out the top five were Hulu’s Under the Bridge, Max’s Hacks (season three) and Netflix’s Baby Reindeer.

Netflix had four shows in the Top 20 to lead all streaming services. Eight different apps had shows on the list.

Amazon Prime Video’s remake of Road House was the top movie on connected TV, according to Power Score.

The other top movies for the month were The Little Things on Max, What Jennifer Did on Netflix, Migration on Peacock and Taylor Swift The Eras Tour (Taylor’s Version) on Disney Plus.

The Power Score ranking is designed to compare streaming shows on an apples-to-apples basis. In calculating its Power Score, TVision, which measures activity across more than 1,000 apps, looks at the amount of time viewers pay attention to the program, the amount of program time available for the season, the program’s reach, as well as the application’s reach.

TVision said it chose that combination of metrics to enable a neutral look at the quality of programming and its unique, inherent ability to draw in viewers — regardless of the scale of the platform or the program’s release schedule.

After a third-party research company last week declared Fallout's premiere audience to be pretty, pretty big for Amazon, the tech giant on Monday finally chimed in on its own show's audience performance — yes, it’s done well. 

The series adaptation of Bethesda Software's popular post-apocalyptic-themed video game title scored 65 million viewers globally in the first 16 days after it was released on April 10, giving it the second-largest Amazon Prime Video debut since The Lord of the Rings: The Rings of Power premiered in September 2022. 

Amazon also said Fallout had its biggest debut ever among adults 18-34 and that 60% of its audience has come from outside the U.S., with the UK, France and Brazil producing "outsized" viewership. 

The series has already been renewed for a second season. 

Fallout the series is executive produced by Kilter Films'  Jonathan Nolan and Lisa Joy, in association with Amazon MGM Studios, with Geneva Robertson-Dworet and Graham Wagner serving as creators. 

Arriving with a reported first-season production budget of $153 million, Fallout arrives at a welcome time for Amazon MGM Studios chief Jennifer Salke and her team, which are competing for production dollars amid Amazon’s currently aggressive posture for live sports rights. 

Fallout, Amazon Prime Video’s latest big-budget TV series effort, has quietly emerged as the platform’s biggest premiere audience draw of all time. 

While conceding the adaptation of a popular video game is “one of the service’s top three most-watched titles ever” as it renewed the show for season two just nine days after its April 10 premiere, Amazon would not provide first-party audience performance data. 

For its part, Penske Media Group research company Luminate said Fallout drew 2.5 billion viewing minutes in the U.S. in its first full week of release, April 12-18. That was around three times as much viewing engagement as the second-ranked show on Luminate’s ranker, Netflix’s Unlocked: A Jail Experiment.

Meanwhile, a PlumResearch data analysis puts first-week U.S.-only viewership for the post-apocalyptic action series, produced at a reported first-season budget of $153 million, at as high as 53 million views and 47 million streaming hours from April 11-15.

That makes Fallout Amazon’s most successful U.S. TV premiere of all time, PlumResearch said, adding that the previous best week for an original was the 28 million views garnered by The Boys during the week of its July 2022 season finale.

PlumResearch said Fallout, which is also available globally, currently occupies around 30% of viewing time in “most” international markets. In the top 15 markets, it generated 91 million viewing hours and 102 million views, the researcher claims. 

The same data suggests that the series is drawing viewers back to Prime Video to complete the eight-episode first season, with 9.7 million U.S. Prime profiles tuning back in to watch. That’s the streamer’s biggest yield of returning customers yet, according to PlumResearch.

“Fallout has clearly been a resounding success for Prime, receiving widespread acclaim and almost instant renewal for season 2,” Plum research director Jonathan Broughton said in a statement. “While the viewing across the first few days of the series has been unprecedented, reaching as high as 45% in some markets, it does remain to be seen how this plays out longer term.”

Unlike Reacher and other Prime Video original shows, Fallout dropped all of its eight episodes at once, breaking a sequential, week-by-week pattern adopted in recent years for series including The Boys, The Wheel of Time and The Lord of the Rings: The Rings of Power.

That likely had much to do with the initial surge in viewership, as collective viewing for Fallout’s first season has already made it the streamer’s second most-viewed property of the year, behind Reacher.

With networks turning over every bit of popular intellectual property to see what might work on television, video games are an increasingly hot source for development. Most recently: Amazon Studios has licensed the rights to Fallout, with Kilter Films, producer of HBO’s Westworld, producing.

Fallout is set in the future, following a global nuclear war. Amazon Studios would not comment on its plans, but Albert Cheng, chief operating officer and co-head of television, said in a statement the game is “an iconic global franchise” with loads of fans and lively storylines.

Amazon’s Fallout plot comes on the heels of HBO’s plans to adapt The Last of Us. The PlayStation game looks at a smuggler escorting a teen girl across a post-apocalyptic U.S. Craig Mazin, who created Chernobyl, will executive produce alongside Neil Druckmann, creative director of the game.

Sony Pictures Television and PlayStation Productions are producing. Chris Parnell, co-president of Sony Pictures Television Studios, called it “the first of many shows we intend to develop with our friends at PlayStation Productions.”

Showtime, for its part, has long been working on a series based on the Xbox game Halo. It will depict the 26th-century conflict between humankind and an alien threat known as the Covenant. Showtime would not comment, but has said the project “will weave deeply drawn personal stories with action, adventure and a richly imagined vision of the future.”

Halo is scheduled to debut next year. Pablo Schreiber, Natascha McElhone and Bokeem Woodbine are in the cast.

The TV projects bring an automatic audience along for the ride. Nearly two-thirds of American adults played video games daily in 2019, according to the Entertainment Software Association, and one has to believe the number is going up considerably in work-from-home 2020.

“Previously subcultured gaming has bled into mainstream culture,” said Sarah Unger, senior VP of cultural insights and strategy at Civic Entertainment Group. “It extends across all demographics.”
