What year was Instagram launched to the public?

Instagram was launched to the public on October 6, 2010. The app was initially available only on iOS devices, and it quickly gained popularity due to its simple and intuitive user interface, as well as its unique features such as filters and square-cropped images.

Within two months of launching, Instagram had already reached 1 million registered users, and by the end of 2010, it had surpassed 1.3 million users. The app's rapid growth and user adoption helped it attract investors and eventually led to its acquisition by Facebook in 2012 for approximately $1 billion in cash and stock.

In 2012, Instagram also launched its Android app, which further expanded its user base and solidified its position as a major player in the social media landscape. Today, Instagram is one of the most popular social media platforms in the world, with over 1 billion monthly active users.
