      Radio vs TV for Boomers

      B&W vs Color for Gen X

      SD vs HD would be Millenials

      4K vs HD for Zoomers

        I’m a millennial and I can’t really tell the difference between SD and HD. Do you mean like when YouTube switches to 360p instead of 1080?

            I recall some people calling 1440p 2K and it really grinds my gears
