How long should a streaming service keep a show exclusive before licensing it out?

Longer than the 2021 consensus assumed, because the industry moved the other way and the studios that pay for windows have been extending them. Universal went from 17 guaranteed days in 2020 to 45 days and seven weekends from January 1, 2027. And the link everyone assumes — that exclusivity lifts streaming performance — has never been demonstrated publicly.

The evidence

The windows lengthened, they did not collapse.

Universal's path: 17 days guaranteed under the 2020 pandemic deal, then three weekends, then five weekends announced March 2026, then 45 days and seven weekends from January 1, 2027. Paramount and Amazon MGM sit at 45 days. A24 at 31 days or fewer.

Netflix committed to a full exclusive theatrical run.

Narnia goes to wide release February 12, 2027 with a Netflix debut on April 2 — roughly a 49-day window, described as the first Netflix title to carry one. Warner Bros. abandoned the 2021 day-and-date HBO Max slate outright.

Licensing out is coming back.

Disney resumed licensing to Netflix in October 2026 — five Ice Age films, Percy Jackson seasons one and two, Soul and Elio. No value was disclosed. Lionsgate's Amazon concentration rose in step: 18% of FY2026 revenue, against 16% in FY2025 and 14% in FY2024.

The assumption underneath all of it is unevidenced.

No rigorous public study shows that a theatrical or exclusivity run causally lifts streaming performance or library value. The best available analysis disclaims its own conclusion. The industry asserts the link and acts on it; nobody has published the evidence for it.

What would have to be true for this to be wrong

If you can measure the counterfactual inside your own service — two comparable titles, one held exclusive and one licensed early, with completion and retention tracked on both — then you have evidence nobody else has and you should trust it over any of the above. The point of this answer is that the public record cannot supply it.
