If your TV has internet capability and can run apps such as Netflix, it is considered a "smart" TV. To use Netflix on your smart TV, you first have to connect it to the internet and buy a subscription to Netflix. You can then find the Netflix app in your smart TV's menu system and start streaming movies and television shows right away. If you can't find the Netflix app or if it's not listed as an available app, you may need to check with the company that made your TV to see if it can be added or if it's not supported on your specific model.
