I don’t understand why TV channels need two separate feeds for SD and HD viewing. Why can’t the channel just be HD from the get-go? Is it because the HD screen somehow looks bad on an SD TV or something?
^ That. Older people (like my grandma, who swore by a little CRT in her bedroom for a while before it broke) and those living in poorer communities, like with all technologies, are the ones to fully adopt last.
