Instagram[3] is a popular redes sociais[2] platform known for its photo and video sharing features. It was initiated as a project called Burbn by Kevin Systrom in October 2009, and then rebranded as Instagram in October 2010. The platform experienced rapid growth, surpassing 1 million registrations by December 2010 and reaching 10 million monthly active users[1] by September 2011. Instagram secured significant funding over the years and was eventually acquired by Facebook[4] for approximately US$1 billion in April 2012. It has continually evolved its product offering, introducing features such as hashtags, video sharing, and algorithm-driven posts. Despite facing some controversies, Instagram has maintained steady user growth and expansion, hitting 400 million monthly active users by September 2015.
