The theory is that many of the news correspondences like to play it up in front of the camera. I tend to agree with that accessement, kind of the same as cameras effect a courtroom trial. There are too many people looking for their 15 seconds of fame.
Interesting so the goal is to dampen down the spotlight for the reporters so they don't attack or grandstand as much. Good insight... could be right. Do you think they are trying to detract people from viewing?
Nobody actually views those things. Be honest, all that's happened is we aren't getting daily doses of clips saying look at this idiot reporter, or OMG Spicer gave this reporter a dirty look. It never was about substance. Have you noticed the complete lack of any actual news coming from these briefings? The reason is they aren't very news worthy. It was the show that people watched.
