The TV in the 90s didn’t have a computer built in where you could download apps nor did have an internet connection. You unfortunately can’t buy a TV today that isn’t “smart”. The same video sources that you watch on your computer, are usually available on TVs - YouTube, Netflix, Hulu, etc.
Back then, they were also essentially the same technology (cathode ray tubes), but the TV had tuner and some analog circuitry to decode the signal.
