well, it's not quite what you are talking about, but i work in a tv station every day. it's my school's morning announcements. :] it's very professional though. the setup in the WPBC room (where we film and broadcast live across the school and record DVDs to send to the educational programming channel) is like this: there's lots of computers. it's all computers and switchboards and dvd players and other things like that. lots of technology.
there's 3 televisions just for the assistant director, who cues up videos, previews videos on each screen during the show, and generally just makes sure the anchors look nice.
the director has several televisions and a switchboard where he controls what is going on. he can preview a camera shot on one screen while another is being broadcasted. then he uses the auto-take button to switch over to the previewed shot. the director is the one completely in charge.
the sound board looks like
this. it's operated by someone who wears big headphones tilted on their head so they can play things in one ear and always have another ear open to hear the director. they control everything that someone hears on the show. and of course, depending on how big the station is, soundboards can be pretty big and complex, and require very talented people to operate them.
the titler computer creates a powerpoint with all the graphics needed for announcements, weather, etc... using a small machine mounted to the top of their computer, they control what shows up on top of the show.
oh, also. there's even televisions in the back. this is so the anchors or people on the stage can see themselves when looking straight ahead. that way, they can make sure they look good.

this is even included in most professional studios, which i've been to.
but yeah, there's all sorts of jobs, with plenty of televisions, machines, and computers all around.
i've been in professional news studios before too. they're very much the same, actually. last time i was in one was for the regional Michigan spelling bee, in which i was a contestant (i got 2nd place, so i didn't end up going to Washington DC for the national competition :< ). one thing to notice is that the studio isn't as big as it seems on tv. this is how the one i was in was set up for the spelling bee:

there were lots of cameras and some televisions and a curtain covering the control studio in the back. there was a podium right in front of the stage, but the way they filmed it (with the upper-left-most camera) made it look like it was far away, and they just managed to steer clear of it with the way the other cameras were positioned. there's lots of tricks to that. that's how it is in the actual room where they filmed it, which can be set up all sorts of ways depending on the show and what you're filming. and if you're filming something like a sitcom or movie, it's much different, where there is no studio audience and there's equipment set up right in front of cut-out houses or scenes.
but yeah, hope that helped, i guess. and remember, google is your friend. i'm sure you can find some images of these things if you google them.
