One screen to rule them all?

TiVo will let users view YouTube videos on the television screens beginning this week. See article.

This on top of recent announcements that Netflix will enable video downloads onto Xbox 360 game consoles, AppleTV enabling web video to tv screen, etc.

Just what TV networks--the cable and broadcast kind--needed: more competition for attention. Only this time the competition is content from their audience. Yes, yes, we'll debate the qualitative differences between YouTube video and HD by land and by air on a large screen...these are temporary distractions that cheap computing power will address.

As the three screens (smartphone, computer, TV) begin to resemble each other--essentially becoming variations in size for delivering the same content in different contexts--one continues to wonder whether it's finally time to redefine the word 'television' to the piece of commoditized hardware it is.
