Employers expect employees to stay up-to-date in their respective field, and today's technology makes this reasonably easy! List several ways that you receive your industry knowledge and stay on top of media and entertainment trends. Tell the interviewer about those daily update emails you receive from organizations who are authorities on media, conferences you attend, and professional organizations of which you are involved. Lastly, it's a great idea to ask the interviewer what resources they refer to for industry trends. That question can start up a great conversation, and teach you a thing or two as well.
