Answer 1

TVs and computers used to use a different method of displaying the image on the screen. ([Cathode Ray Tube](https://techterms.com/definition/crt))

They used to work like a projector, inside the back end of the tv box a device would shoot the image onto the TV/PC screen.

Now we have liquid Crystal and light emitting diode displays which are essentially a sheet of individual pixels that change colors to represent the image being displayed.

Bundle that with shrinking the size of the hardware inside (basically by squeezing everything closer together than we could decades ago) and you’ve got smaller devices.
