The only reason to set up a satellite link between a news anchor and a roving reporter is distance. If one is in the studio, and one is on location, it makes sense.
What doesn’t make sense is setting one up when both people are sat in the same car park. Which is exactly what CNN did recently.
This annoys me more than it should do, quite frankly. And by this I mean the CNN duplicity rather than Jon Stewart’s efforts to bring it to wider attention.
I hate being lied to, especially by a news organization that is meant to divulge the truth, and which a lot of people believe implicitly.
