This question is very broad and you have not included in your question the parameters for your answer. Does the prompt ask for a paragraph, or an essay?
Because it is so broad, this appears to be a question asked at the end of a unit to assess what you have learned.
Begin by looking over your notes for anything about the development of film and media. Write about the beginnings of film and media and use your notes as supporting evidence. Notice about how film and media has changed over the years and write about that. Think about what direction film and media might take in the future to answer the second part of the question.
