[Scan-DC] DC TV Station helicopter(s)

[andrew]

My search ended up with no answer to my question. I know that at one time some or all of the DC TV stations had their own branded helicopters but at some point they abandoned that and some or all of them went in together and agreed they would share helicopter footage in order to not have the high cost of having an “exclusive” helicopter to their own. 

Anyone know any facts behind this? If some any information on the helicopter itself and what kind it is and who runs the helicopter? Looking for a tail number of it as well.

Thanks in advance.
