Mainly because there's hardly ever anything good to watch anymore: you've got talent competition shows where the competitors care less about whatever talent they may have, and more about the fame and fortune they want; you've got reality shows that have little to no reality to them at all; you've got shows that actually celebrate morally reprehensible actions (like those teen mom shows Drtooth recently pointed out); you've got trite and tasteless sitcoms that are all about toilet humor, characters jumping in bed with each other, and certain cast members leaving because they think they're now big enough stars to make movies; you've got celebrity gossip shows; among other junk.
