Instagram is a online photo and video sharing social network. It was started in October 2010. The service was acquired by Facebook in April 2012. Instagram has grown rapidly and had over 100 million active users as of April 2012
Getting started is fast. New users can get started with the service by downloading the Instagram app through the Google Play or Apple App store. There is no way to get started on Instagram from a non-mobile device. After downloading the app to your device, you simply enter name, username, email address and a brief description and you’re ready to go.
Although you can see your profile in a web browser and edit basic profile information such as email address and bio description, you need the app to upload, comment and tag photos.
If you are using Instagram for your business or blog, there are Instagram Badges you can download to put on your site to attract followers.
