Hard to say. Wilks was an investment firm first and foremost. So, if station prices get low enough, it's possible it will be back.
As for other operations, the company used to be majority owned and controlled by Wicks, which owned radio and TV stations itself for a few years and also owned a traffic scheduling system. I understand the traffic business merged into another one not quite 10 years ago. I'm not sure if Wicks or the other company became the dominant one.
