SAN News
SAN News, (presumably standing for San Andreas Network), is a news network appearing in Grand Theft Auto: San Andreas.
Vehicles
The network have their own helicopters, the News Chopper, which can be seen flying around the player when a high wanted level is achieved. The helicopter doesn't affect anything, but Carl can still shoot it down.
For on-the-ground operations they use the Newsvan but, unlike the News Chopper, it is not deployed on the streets based on the wanted level, and can be found driving about the various streets and highways.
Broadcasting
It is never said what else the station broadcasts or where the television station is, but a Newsvan can be found beside the radio tower on Missionary Hill.
