OK maybe not possible, but I truly long to see the US broadcast networks regain the dominance they had in the 1980s. If we lose broadcasting, we lose a sense of community. Maybe not realistic or possible though but I really wish.
I'm also tired of the more recent business practices of the big networks over the last 20 years.
I do long for that cosmic event where the 1980s sense of things are renewed again.
If the fad of "cord-cutting" did not do it 4-5 years ago, then I doubt it can be accomplished without a drastic change to the broadcasting methods. While the DTV technology is somewhat new and features infinitely improved quality, the basic method of broadcasting has remained more or less the same for decades. Coverage is lackluster in parts of cities without monstrosities being installed outside. If you are fortunate enough to live close to the source or in an area with few obstructions, great, but in most cities, you are lucky to get about half of the main networks in any one spot without those finely tuned eyesores.
Imagine if your phone could only work in a specific local calling area. Broadcasting innovation somehow died at the local level. At a certain point, it became good enough. Cable gets some of the blame, but the government, and more specifically the FCC, takes the big hit here.
If you make broadcast significantly more accessible to a large geographical region, then it might just make it dominate again. Basically the widespread access to high speed internet and other instant technologies has ended any hope of broadcast becoming dominate ever again.
