Books on Media Consolidation

Looking for a recommendation or two for books pertaining to the continued consolidation of ownership in the media market (entertainment, broadcast news, newspapers, and now maybe even TikTok via the Ellisons) and the downstream risk for manipulation/control of messaging. Googling and Goodreads searching hasn’t returned many promising leads.

Ideally looking for something published in the last 5 years given how rapidly this is evolving.

Thanks in advance.
