Samsung has announced that Netflix will no longer be supported on some of its older smart TVs.
From 1 December, the Netflix app will no longer work on some 2010 and 2011 models due to "technical limitations".
Seven older Roku streaming sticks will also no longer support Netflix from December, Roku told Digital Trends.
Netflix can be watched on smart TVs, set-top boxes, streaming media players and video consoles. Users can check if their devices are compatible here.
"Samsung was recently notified by Netflix that as of 1 December, the Netflix app will no longer be supported on selected 2010 and 2011 Smart TV models sold in Canada and the US," Samsung said in a statement.
"For consumers with these models, there are still many other devices supported by Netflix that can be connected to a Smart TV in order to access the app."
Jim Martin, editor of tech reviews website Tech Advisor, says consumers should check whether any of the other devices they own can be used to access Netflix.
"It's partly the price of being an early adopter," he told the BBC. "Technology moves quite quickly and nothing lasts forever."
He added that people who want to keep accessing streaming services on their existing smart TV could plug in a streaming stick.
Roku said the older streaming stick models that would no longer support Netflix included the Roku 2050X, Roku 2100X, Roku 2000C, Roku HD Player, Roku SD Player, Roku XR Player and Roku XD Player.
