Best Buy used to have a fake internal website that looked exactly like their actual internet website, but with marked up prices, so they could price gouge in-store customers
CRT's have a long afterglow so has plasmas, so there is defenetly no flicker as the cause of dogs not being "able" to see TV.
LCD's on the other hand was much hated at first because they could'nt refresh fast enough and that made them flicker.
Back then pc graphics cards didnt have refresh rates past 70Hz because there was no "need" for it as the CRT's could'nt keep up.
100 years ago some films was done in 16 pictures/second, does that mean that we cant see then because we would "only" see flicker?
