Netflix's main advantage is its accessibility across multiple platforms. Users can easily access the platform's extensive content library on their browser, phone, game console, or TV. However, due to the company's long-standing presence in the streaming industry, certain older devices will eventually no longer be supported. Recently, Netflix has discontinued support for a range of devices, including older Toshiba, Samsung, and Sony TVs. Users of these devices are now required to upgrade to newer models in order to continue enjoying Netflix. Additionally, this mass discontinuation has impacted some gaming consoles like the PlayStation Vita and PlayStation TV, as well as older Blu-Ray players.
There does not appear to be a comprehensive list of affected devices, as Netflix is only notifying affected users privately instead of making a public announcement. It seems that most, if not all, of the affected devices are between 10 and 14 years old. The Netflix notice provides a link that redirects to a generic list of supported Netflix devices, which includes various smart TV brands, streaming device brands, and game consoles.
The reason for removing these devices is not immediately clear. It should be noted that age may not be the only factor, as Netflix is still compatible with the PlayStation 3, which was launched in 2006—approximately 17 years ago—making it possibly the oldest device still supported by Netflix at the time of writing. The positive aspect is that if your older device is a TV and it has an HDMI port, there are still options for watching Netflix. You simply need to purchase a streaming device, such as a Chromecast or a Roku, and you'll be ready to go.
