If I had my way, the TV landscape would be a lot sparser.
I would probably start with reality TV as a whole. Shit like Survivor (is that still even a thing?), Amazing Race (Again, does that even exist anymore?) and The Apprentice is just a seething miasma of artificial drama with fake people in some overblown, overproduced perversion of an approximation on human interaction as made by some higher-up Shoggoth in a boardroom. Seriously, fuck that shit.
I'd then move onto the spawn of reality TV: the 'talent' shows and the 'life and times of one of you organisms' garbage that the History Channel seems content to spew forth under the guise of 'history made everyday'. Fuck off. No one gives a ha'penny jizz about what some hicks in some backwater swamp are doing with themselves. I don't know how this worhtless shit passes for entertainment.
As for talent shows, while they can, on rare occasions when the planets align, the heavens open and hell freezes over, turn out some genuinely talented people, its primary goal seems to be providing random idiots a means to embarrass themselves on national television, and to make one question the value of a human life. This was fantastically demonstrated last year on Britain's Got Talent, when two monumentally talented (well this is assuming they weren't lip syncing. It would be incredibly upsetting, but I wouldn't be at all surprised by it) 16 year old opera singers were beaten out by someone's dog doing tricks. Whatever god is out there, it has a sick and twisted sense of humour.
The next course of action would be to have the History Channel, the Discovery Channel and the National Geographic Channel summarily executed for polluting their broadcasts with insultingly pandering shows about hicks in swamps, hicks making moonshine, hicks fishing for catfish, hicks in another swamp, cold hicks in planes, cold hicks in trucks, cold, wet hicks on a boat, warm, wet hicks on a boat and various other permutations. Most likely I'd spare the specialised channels like Discovery Science, Discovery History and maybe NatGeo Wild, if I'm feeling merciful, since they still retain, for the most part, their original focus. History Channel, however, will taste my limitless wrath for basically homogenising everything and turning all of its underlings into copies of itself. While it wasn't unforeseen, with bullshit like the DMZ on the now disbanded Military History (replaced with H2) where they decided to air the same bullshit as History, like Ancient Aliens and Pawn Stars, on Military History.
There's more that I could list but I'd just get mad and probably end up rending existence in twain. Best to avoid that.
