This was a difficult decision for us, but we think we arrived at the best decision for our company, and we are pleased that we’ll continue to have a presence in the Richmond and Chattanooga markets through the iHeartRadio platform, Premiere Networks, the Total Traffic and Weather Network and the Virginia News Network.”
