RE: Doesn’t mean Hannity has to BE in New York to host the show
What about his TV show?
If he has a panel (as he usually has), does it mean the rest of them have to be in NY and he has to be linked to them remotely?
Nope, they can all be in different locations. Often times Hannity's guests have been in Fox News Stations in other parts of the country, some have been via Skype or via a commercial web-based live streaming service such as U-Stream.
The technology has really gotten to a point where Web Streaming from personal/home studio's with professional quality is negating the need for formal studio's.
I'm an amateur radio guy, I stream online whenever I'm on-air via my QRZ page so my contacts can see me and my station. That's becoming increasingly popular. The video and audio streaming quality I'm able to deliver with a set (3) of mid-priced webcams and a studio quality microphone (Shure 58) is near broadcast quality. If I were to have better video streaming camera's I could easily do broadcast quality from home.
