Instagram is a visual social media mobile app, where the user’s profile is composed of photos and videos, and the feed shows all the photos and videos posted by the people who the user follows (ordered by an algorithm, instead of chronologically like it used to be). Instagram also has a temporary content component: the Instagram Stories, but it has evolved so much during the last few years.
Instagram has been around for almost a decade, but it has become especially popular during the past couple of years (although in the beginning, it gained an incredible amount of one million users in just three months of existence, and all organically!). And rightly so: if you recall, the human brain processes images way faster than text. Visual is easy and that is what people want when they log in to their social media.
In 2012, Instagram was bought by Mark Zuckerberg, the founder of Facebook, so the two platforms can easily be connected and managed side by side, which will definitely make your job easier, but I will get into that later.
Today, Instagram is the number one photography app, that is used by all kinds of people: from the individual who just wants to take amateur photos of his or her daily life, to the professional photographer who only posts high quality visuals. It is available for both Android and iOS, so you do not need a specific device to create your profile; and you can also access it on your computer, although the functionalities are limited (it is more of a solution for desperate times, like if you ever lose or break your phone).
