Can technology over time improve TV media?

Are our expectations of TV media every going to be reached? Considering the new channels and 24/7 news coverage we now have via cable and internet, is it any better? Access is up, but TV news is still lamented for being at the lowest common denominator for what sells. Won't each media channel always be limited by varying degrees of place, space, technology and all the other factors that Fry mentions? Should we expect TV to give us "our understanding of the environments and people in those places, what that says about us, and what that says about the communication media we attend to and rely on for learning about and sharing information about other places and people"? Could changes in technology open an opportunity for TV news to become more informational, to understand "nature and environment," and how could and should the "TV news system" change to accommodate this?
