What makes a good radio/TV news story?

Even though it is obvious that stories within the news, radio, and television all have the same objective in creating good news, they all go about it differently. Radio and television have time restrictions and tend to be more censored in what can be talked about as opposed to print. Written news has more leeway in that they may be limited on space, but the stories still tend to be longer. TV and written news have the ability to use visuals to aid in their articles but radio on the other hand does not. Radio has the ability to use audio (TV as well) where as printed news does not.
