Instagram recently announced they now have 500 million users. The success and growth of this online community comes as no surprise with the social media boom in recent years. Proving its mastery of the mobile domain, Instagram’s user base is growing faster than the overall social network usage – Growing 15.1% this year, compared to 3.1% overall growth for the social network sector. The recent rebranding efforts, although largely criticised, hasn’t deterred the users. Critics thought Mark Zuckerberg was crazy paying $1 billion in 2012; Instagram was labeled a risky purchase. The chance has paid off with the growth not expecting to stop here and users expected to double in the next four years.
