Trunked radio was also sold as two way radio service to small businesses in the '80s. The WACX tower site had a huge roomful of Motorola trunked base station equipment. It bugged me that they would install mobile radios at the tower site, leaving both fences open to anyone who wanted to drive to the tower. That was in 1987.

You can't have a sense of humor, if you have no sense.
Motorola came out with trunked radio systems in the late 1970s, they were expensive enough that only large organizations could afford them, only partly due to FCC licensing costs. Of course public safety and similar agencies got first pick when they could afford them.
