A press release telling about "Stevie, Water-Skiing Squirrel" will never get that talented mammal on TV news. But that same press release, accompanied by video of Stevie jumping over mini-ramps in an inflatable pool, will make news nine days out of ten.
Words on paper or screen alone do not make a TV story. If you want to crack TV news or talk shows, you must demonstrate that you have a “visual.”
A visual is images or video that accompanies words. TV needs something that moves or talks to tell its stories.
If it looks interesting or nice, that’s a plus. They will shoot video; you don’t need to. But often you do need to suggest what to shoot.
