Among 14-49 year olds, 'Sommerhaus' saw a fourfold increase, while 'Love Island VIP' saw up to a sixfold increase.

In the second week of its run, the ARD series 'Babylon Berlin' significantly increased its streaming reach to 1.893 million weekly net viewers, leading the cross-provider ranking of all AGF-measured offers. The free-TV broadcast during the same week provided an additional attention boost. The US series 'Reacher' on Prime Video followed closely with 1.854 million. Meanwhile, the Sat.1 reality show 'Villa der Versuchung' on Joyn fell below the 500,000-viewer mark for the first time, reaching only 0.48 million weekly net reach. Other RTL reality formats like 'Sommerhaus der Stars' and 'Are You The One' performed well, while 'Love Island VIP' started slightly below last year's premiere. The data, provided by AGF Videoforschung for calendar week 38 (Sept 14-20, 2026), measures weekly net reach of program brands on streaming platforms, excluding YouTube and social media.

Convergent Ratings Boost 'Die Verräter' by 46%
