If I were Prime Minister, Radio and TV News shows and staffers would be gone in a flash.
If humanity lost all its radio and TV news overnight, it won't lose a thing--- just as long as we still had long form texts with pictures in our print media. Even better, long, long form texts and plentifully pictures with a few links to short audio and video clips, available 24/7/365 online.
I loved radio and TV, though I generally never go near them these days. I think they are/were wonderful pipelines for delivering music and movies, sports and live events - even current affairs shows with five pundits yelling at each other.
Radio and TV do emotion and drama wonderfully - but they don't deliver detailed explanations very well. They don't provide the rewinding-ness of video and records and the multi-column-ness of newspapers and magazines.
