Tube sets were all analog while today's sets are all digital. Digital requires about one bazillion components to do the same function an analog circuit consisting of a few reactive components and a vacuum tube can do.
But give me digital any day. The math is easier.
Let's say you want your wholly analog TV to remember that you were watching channel 24 when you switched off, & want it to come back up on channel 24 when you turned it back on. Well, if Wang had invented it yet, magnetic core might be around, but it cost 10 times more than the TV set - let alone the logic to implement it.
