The first satellite news truck, Conus-1, is already a museum piece, but it was vitally important to the 80's growth of news broadcasting on cable tv

restored by the B R Howard company, it was built on an F350 van chassis, which couldn't handle the weight, and then built on an '84 GMC truck frame because additional components added to the vehicle (control center, cargo bed, and a hydraulic satellite disk boom) were heavier than anticipated.

Satellites were key to tv affiliate stations getting news to and from the networks (ABC, CBS, NBC, CNN) which broke the networks control over the news stories that were selected. In covering breaking news, local stations have the variety of resources to choose from of networks or affiliates. If you are interested enough you can read all about it I learned a bit from this Google book
