Trends and Factors

What 3 trends do you see in computer evolution? AND Why?
Three trends I see in computer evolution involve design of computers, the scope, and the programming on it. The design of computers have become smaller and smaller and smaller. Computers used to be the size of rooms and now are the size of index cards.Th reasoning for this is because it makes it easier to carry around. The scope on computers has also changed. There are games,programming systems, many search engines, websites, and even cameras. This is because of needing and wanting more abilities on the computer. The programming on computers keeps growing and growing, going from 97-2000s, to 2013 only, 2014 only. This is because they come up with different tasks that can be accomplished and need to update it.
Name 3 factors that drive technological innovation?
One factor that drives technological innovation would be new inventions such as phones and making phones do everything a computer does. Also social networking and social marketing.
