What Internet TV needs in order to compete with cable

— Broader selection of both current episodes of popular shows and of classics. Current offerings are spotty, with individual episodes and entire series appearing and disappearing without warning.

— Live video aimed at large-screen TVs. There's little out there right now, and what exists is generally of poor quality, suitable only for viewing in a small window on a computer display.

— High-definition video. Even if you have a fast connection, Internet sites today can stream video only in "standard definition"—roughly what you see on a standard, non-HD channel. As network speeds improve, the sites should be able to deliver true HD video.
