Has Instagram always been a social media site?

I went to download Instagram and try it out through the AppStore on my iPhone. When I did I noticed the program was saved to my cloud so I must have downloaded it a long time ago. I remember downloading a bunch of different photo editing programs and not liking them so I deleted then but that was a long time ago. Now all I hear is people using Instagram as a social media site. So I'm wondering was it always that and I did not know or was it just photo editing at first?

Yes, it has always been.
