One of the Earliest Examples of Social Media's Impact on a Brand

One of the earliest examples of social media's impact on a brand occurred with Kryptonite,which has been a leading producer of bicycle locks for more than three decades.How was this firm impacted by social media?

A) Users contacted the company about sponsoring a bike competition and this led to social media product endorsements by all types of different companies.
B) Users posted videos showing how the bike lock could be employed for other uses around the house,and this led to an increase in company sales.
C) Kryptonite enjoyed steady sales until negative product reviews on Yelp and YouTube drastically reduced company sales,causing the firm to go out of business.
D) Users posted videos showing how the company's bike locks could be opened with a pen and this forced the company to change its design.
E) Kryptonite was a little-known brand until social media users began raving about the company products,leading to an unprecedented increase in sales.
