“After the streaming-video giant released the second season of the comedy “Grace and Frankie” in 2016, its product team put up an image to promote the show to U.S. subscribers that only included Ms. Fonda’s co-star, Lily Tomlin. Tests showed that more users clicked on the show when the photo didn’t include Ms. Fonda. The decision set off a high-pitched internal debate. The Los Angeles-based content team was concerned that Netflix risked alienating Ms. Fonda, and that the move could even violate her contract, while the tech group in the Los Gatos, Calif., headquarters argued the company shouldn’t ignore the data, according to people familiar with the discussions.
In the end, Netflix chose to put images that included Ms. Fonda back in the mix.”
