Each medium has strength the other does not. Each makes use of strong points that the
other lacks. Television news is like a having a fast food meal whereas reading newspaper
is like having a ten course dinner. The ideal seems to be, if one has the time to both read

primarily established to cover the news and later on they added entertainment. On the
other hand television was mainly invented for entertainment and then it became an
effective news medium.
