We often hear people say dismissively: "Yeah, most of what's on TV these days is junk, not worth watching." The point-of-view seems to imply that the ones saying it have actually watched "most of what's on TV these days'" so as to make a proper evaluation, which says more about the speaker's use of time than the media content he is so quick to denigrate.
I wouldn't know whether such things are true or not. Although I do not presently have a television, I do watch some TV when I get a chance—but always what I choose to watch, as contrasted with mindlessly flipping through channels. Therefore, regardless of what generalized platitudes may be uttered regarding the overall quality of television programming, most of what I watch on TV is not junk, and is worth watching.
