The part of CMG advertising the capability is CMG Local Solutions. CMG itself is owned by Apollo Global Management and Cox Enterprises, which includes the ISP Cox Communications. CMG operates a wide array of local news television and radio stations.
Cox Enterprises isn’t some random company. It’s one of the largest privately owned companies in the US. They are somewhat capable of doing things like this.
Having experience with Cox Enterprises, it’s just a massive amalgamation of disparate acquisitions that have never been remotely brought together in a meaningful way so it is a slightly dubious claim. This would require much more coordination across entities than I feel is possible with the CMG I knew of pre-pandemic.
