When I say winning concept, I mean that it was made to stay, just like print, telephone, radio, television and radio. Each have enough advantages so that you can't eliminate them no matter how hard you try. Print is amazing. As long as you have some light, you can sit down to read a book, document or a newspaper almost anywhere at any time of the day. Also, print is so flexible and you can keep it archived as long as you want.
Radio is very simple.
It brings you news, music or shows and you can listen to it while doing something else. Television is the powerful combination of sound and images. These winning concepts have been threatened by newer ones over the decades. It was predicted that radio would kill the newspaper and that television would kill them both. It's silly when you look at what happens today.
