For companies, Instagram can be used as a tool to connect and communicate with current and potential customers. The company can present a more personal picture of their brand, and by doing so the company conveys a better and true picture of itself. The idea of Instagram pictures lies on on-the-go, a sense that the event is happening right now, and that adds another layer to the personal and accurate picture of the company.
