✔ 最佳答案
you need to think in three different areas:
1) Media
2) Responsibility
3) act ethically
Today, the media do not only consist of TV, radio and newspaper. Aas a matter of fact, the list goes on with the online and mobile counterparts, podcasts, cellphone broadcast and forums and even chat-rooms. So, how to limit your essay to a manageable section is crucial.
From then on, you can talk about "responsibility" and "act ethically". Without any limitations to the term "media", you will find yourself inside a trap of quicksand.
