It is attributed to Samuel Clemens, “If you don’t read the news, you are uninformed. If you do read the news, you’re misinformed.”

As with most humor, it is only funny because of the element of truth in it. Even back in his day, newspapers weren’t exactly accurate in their reporting. Of course, back then, there was no radio or TV. However, it would appear that to keep the saying true, both the radio and TV is making sure to maintain the tradition.

Indeed, it is true that it is difficult to find those publishing the truth, regardless of the medium.
