Besides the obvious benefits to education and the exchange of information, think about how the internet has revolutionized banking - bill pay online, online banking, money transfers, international transactions available to individuals with the click of a button - all of these things have changed economics for good.
In developing countries, this gives them a relatively cheap and easy way to gather information as well as to communicate with the outside world. It has made the government more efficient and able to share technology and information from the outside world.
Socially, I could argue that it's made humans on average spend less time in face to face or voice to voice communication, and more electronic communication - email, text, bulletin board, etc. In this case, you and I are interacting on this subject as teacher and student, but will likely never meet or speak to each other directly. This has both benefits and drawbacks. One could also say this has made us less patient as a society - we tend to want information instantly, and if we can't get it, we view it as a real inconvenience and we get easily frustrated.
