Not directly about media manipulation, but I recommend The Demon Haunted World: Science as a Candle in the Dark, by Carl Sagan. It is mostly about how to be skeptical about claims that people make, and goes through many cases of how different groups try to manipulate people and trick them into believing false ideas. The audiobook is read by Carey Elwes too, which is a plus :)
If you want to dig in really deep, Horkheimer and Adorno wrote about the “Culture Industry” in the mid-20th century and how even outside of working hours, we are still forced to perform a sort of labor in the consumption of media through our leisure time, movies, tv, music, etc. It’s not so much manipulation of the obvious media like news and such, but a far more subtle mechanism that tells you not only what to desire, but how to desire. The whole thing may be more complicated than you want, and this was a very reductive summary, but I find it to be prescient even 75ish years later.
