Could you maybe talk about something you experienced where you saw the communication- like have you done some work experience/shadowing, or maybe read a book or journal articles about it? Or an online lecture series? They might seem more 'academic' than referencing a tv show? So finding something that details that same communication that interests you, but in a more formal way.
The best thing though is to write something that is specific to you, and about which you are passionate. It is best to be genuine, as that will convey to the readers, so if you do decide to go with the tv show because it is where your interest started, remember to then reference more academic sources later.
