The historian in me always wants to look back at how this sort of media control has played out historically, so thinking about examples like William Randolph Hearst, Henry Luce, David Sarnoff, Axel Springer, Kerry Packer, or Rupert Murdoch across newspapers, radio, television, etc. might be interesting.

Tim Wu's The Master Switch is pretty accessible in this area.

On the intercultural front, the language (very careful public relations and "corporate speak") used in this leaked audio file of the most recent Twitter All Hands phone call might be fascinating and an interesting primary source for some of the questions you might be looking at on such an assignment. https://peertube.dk/w/2q8cdKR1mTCW7RyMQhcBEx

Who are the multiple audiences (acknowledged and unacknowledged) being addressed? (esp. as they address leaks of information in the call.)
