The digital age has made obsolete the CRT TV, and I'm not even talking about the HD CRT TV. I'm referring to standard definition CRT TV with only 3 types of input: S-Video, RCA, and RF coaxial. Consumers are throwing out (hopefully recycling) CRT TVs and replacing them with high definition flat screen TVs (plasma, LCD, LED, etc) with the purpose of watching high definition television programs over air, cable, fiber optic, etc. However, the internet age is changing the landscape of traditional TV. Instead of watching TV when the broadcaster wants you to watch the program, consumers are watching TV when they want to watch the program. Content providers such as Hulu, Crackle, TV.com, YouTube, Netflix, etc, allow consumers to watch content on their own schedule.
What does this have to do with obsolescence? To accomodate the largest number of internet users, online content is generally 240p (320x240) or 360p (640x360). This is lower than the lowest definition flat screen HDTV (480p). Now, the question I ask is, if you want to watch internet content in the comfort of your living room couch, why do you even need an HDTV?
The answer, you don't.
