Oh but they will: https://gracenote.com/. These people sit and watch TV, note down every event taking place then sell the data. Search for Infostrada and how it came under Gracenote. That's where the info like "this is his first X since the game Y Z years ago" comes from.
If you're good enough at it, I suppose someone would. (There are television critics after all.)
But I'm just curious: if someone were to give you a living wage to do nothing but watch TV all day for the rest of your life, how many years do you think might go by before you would start to ask yourself, Is this really what I want to spend my one, exquisite, irreplaceable life on?
