How did Instagram make it ?

For my research project I would like to get more information and find out "How did Instagram make it ?". Instagram passes 50 million users and adds 5 million users a week, it is a huge part of our society, I myself is pretty much hooked on it. It is easy to navigate , it is not cluttered with different advertising's, you can follow who ever you want and it gives people who do not know how to use photo shop an option to edit the pictures in a simple way. What more can you ask for ?
My first step in the research project would be to narrow down the actual owners/company that operates instagram. I would love to know who started it , I would also like to find out how long it took for the instagram to gain it's popularity and how they did it. There is not that much information available on the Internet, but I believe it could be a good challenge , plus it is something that I am interested in.

New Blog, New Start , New Media

I was caught by surprise when I realized that I already have a blog and did not need to create a new one. Aapparently I totally forgot that we had to create a blog for my Political Science class a couple of semesters back and discuss different types of article amongst my classmates. I am pretty much new to blogging but I hope I will get a hang of it. I am not sure how to find my classmates and comment on their blogs and see what they do differently , but there is nothing that Youtube can't do, so I will research and find a manual on how to use it properly. It is amazing to me how one can post videos on their blog, it's pretty cool. I am so happy I took this class because I am really learning a lot of new benefits of new media =) It's a new start and I am ready to give blogging a shot !
