The Economist thinks that media is diverging into blockbusters and niches—with everything else struggling.
Why are blockbusters still doing well in this world of almost limitless entertainment choice? First,blockbusters are the common topics that people talk about with their friends.Second, all that technology that has made niche content so much more accessible has also proved handy for pushing blockbusters.Third,in a world of growing entertainment options that make people freaking out, it's easier for some people to choose what others are talking about or what they have heard.
So,is the increasing polarization of media products into blockbusters and niches a good or a bad thing? Of course it is a challenge for media companies.But is a boon to consumers.Media companies must raise their game to outshine others.Creative types must learn how to move between big-budget blockbusters and niche, small-budget fare, observing the different genre and budget constraints that apply in these worlds.
So, the growth of those niche products grab the market of middle class's instead of blockbusters'.It comes to a conclussion by The Economist that there are only a few things that can be guaranteed to delight large numbers of people.Thus the future of blockbusters is stable.
