"The Problem with Jon Stewart" was launched in Sept 2021 on Apple TV+. However, the show's ratings have been very much failing to meet expectations so far.  

Stewart's competition is doing much better, and people were expecting the show to perform on par with John Oliver's similarly-themed "Last Week Tonight" show, which apparently pulls in close to a million viewers per episode on average.

According to the New York Post, "The show's first episode was seen by just 180,000 US homes in the first week it debuted last fall, measurement firm Samba TV said. That number dropped to 78 percent to 40,000 by its fifth episode, which aired in early March."

Sad to see.
