资料：The movement of consumers from public social media to private messaging has been so rapid that Business Insider reported that the combined usage of the top four messaging apps now exceeds the combined usage of the top four social media apps。Falling data prices，cheaper devices，and improved features are helping propel this growth。Why the hunger for private messaging apps？ Perhaps people are becoming more interested in actually communicating rather than broadcasting。Maybe we don’t want personal and private lives merging any more and we want control over our different social circles within these messaging apps。As my 16-year-old nephew put it，“My friend posted on Facebook and we made fun of him。We only use Snapchat now because who wants to put everything in public all the time？ This just connects me with my real friends。”Social media won’t go away，but traditional social networks may become less important to certain groups。The rise of more intimate channels presents new opportunities，and perhaps perils，for marketers。What is NOT the reason for the growth of private messaging apps？
A：People are tired of social media.
B：App’s improved features.
C：People are demanding for real communication.
D：Cheaper data and devices.
A
