After it was introduced in 2014, not many people bothered talking about the Hulu app on PS Vita and PS TV despite being ad-free. Well unfortunately the app is finally being talked about, but not for a good reason.
The app is completely gone from the PlayStation Store and apparently according to Reddit users on r/Vita, you can no longer even watch content on it anymore.
PlayStation Vita keeps on dying quicker and quicker and sadly this is a final nail in the coffin for many people that used the console for a multimedia device.
Netflix is still thankfully on the platform.
