I'm wondering if this is an essay topic as well, as Will mentioned. If this is the case, my goodness, there are so many directions you could go with this! It also depends if the assignment allows you to respond in more creative ways, or expects a standard five-paragraph essay construction. As stated, this is a pretty broad subject.
Nonetheless, what about thinking in terms of the past in order to frame the present and envision the future? Maybe you can select a specific technology and follow it over time. Take the TV. Before TV, there was radio. Before radio, there was print. But after TV, we now have streaming media and the internet for entertainment delivery. And our cell phones, tablets, and even our vehicles now deliver media and entertainment content to us wherever we are! From having to buy a newspaper to get the day's news to streaming news in our vehicles in a relatively short timespan of human history. Where will we go from here? What will the TV become by the time you are 50 years old? So many options. You could pick any technology to focus on - in fact, that might be a more fun and more productive approach - focus your research.
Broad subject questions can often cause students paralysis of thought - with so many potential directions, where to go? I often find that students benefit from focusing. Narrow the umbrella of the topic down to a manageable subtopic that you are interested in!
You can do this!
