Total Traffic has lost quite a few stations in recent years. All the Audacy stations took their traffic in-house. That includes all the All-News and Talk stations, WINS, KNX, WBBM, KCBS, WCCO, etc. Also cancelling service were the SiriusXM 24 hour traffic channels. And all the Salem stations went from all day news and traffic (some even overnight and weekends) to only morning drive on weekdays. The rest of the day, Salem stations only run the company's own Townhall News, no more local news or traffic from Total Traffic.
But Total Traffic still has all its co-owned iHeart stations and most Cumulus stations, as well as some other big owners. So that is still a large number of stations on the roster.
