In my opinion the most important aspect of the Internet gaining wide acceptance in the United States would be google or internet browsers. I think so because it has made learning quicker and more efficient. Pretty much any question you have can be answered by a click of a button. Now day's you can order groceries, fast food, you can shop for clothes or do just about anything thru Google. My kid's will be riding in car's that drive themselves probobally thru an internet browser company. So like I said, In my opinion the most important aspect of the internet gaining wide acceptance is Google.
