I'd ban all talent shows, reality shows, celebrity talent shows and celebrity reality shows.

And Ant and Dec.

Same here but no idea about the latter.

I'd have a network only playing classic television shows. Unaltered and in their original broadcast versions. All HD broadcast.
Mission: Impossible (1966-1973); Mission: Impossible (1980's); The Saint; The Prisoner; Space: 1999; Doctor Who (Every Doctor, From Hartnell to McCoy); Remington Steele; Rawhide; Maverick; Quantum Leap; Superman and alot of mini-series.
Another channel would be for National Geographic type stuff and that show Leonard Nimoy hosted way back when. More of a retro-History Channel.
Have another channel showing single season shows such as The Flash; Timecop; Now and Again; and many others.
The Gojira/Godzilla and Kaiju channel. Showing nothing but the original and in Japanese versions of Gojira and Kaiju films. All OAR'd and with subtitles.
The Movie Serial Channel. Rotating network with literal weekly cliffhangers. For each day of the week, a different classic serial with the next chapter the following week on its timeslot in true serial fashion. Lots of Flash Gordon; Dick Tracy; The Shadow; and others.
A network in HD and where everything is in OAR where they show films not even on DVD. Perfect for preservation efforts. High Road to China; alot of Robert Montgomery, John Garfield, Errol Flynn, Stewart Granger and alot of other underrated actors. Alot like TCM but only like I mentioned.

Quality TV instead of all that Reality shite on now. I'd cancel all of them i.e. same way Moth3r would. And have no more. Remember when MTV was about music videos instead of all that reality-shite? I'd have them come back to form.
