I would be curious how the financial wires got crossed.
I would have assumed residuals were proportional to views, and views valued proportionally as contributing to subscription demand. And it would be a rare viewer to watch one show like that, over & over. I.e. only upside. Something went sideways.
After Year 1, WGA/SAG residual formulas decrease: Year 2: ~80% of Year 1 Year 3: ~55% Year 4+: sometimes stabilize at a “floor” rate
So what did they do? They ran it for a few years, ran the numbers, realized that Westworld was no longer profitable on the platform. (Profitable would have to mean draws enough new subscribers to the platform). AND THEN - Warner Bros. Discovery made new deals with other platforms with ads. I think you can still find Westworld on Tubi and other ad-supported platforms that actually pay Warner licensing fees.
