Question:

A column on bloomberg.com discusses whether tech firms like Google, Apple, Facebook, and Amazon will be able to maintain their high market shares indefinitely.

i. Google in online advertising
ii. Apple in smartphones
iii. Facebook in social media apps
iv. Amazon in online retailing
b. For each barrier to entry you identified in part (a), briefly discuss whether technological change is likely to reduce the importance of the barrier in the long run.
