Instagram Adds Video

Video is coming to Instagram. Instagram co-founder Kevin Systrom officially introduced the rumored video functionality to an on Thursday.

Described as "everything you love about Instagram — and it moves," video is designed around three core principles:

• Simplicity — It needs to be easy to use and edit

• Beauty — "We need to do to video what we did to photos."

• Community — Instagram continues to look and work the same way when it comes to sharing and viewing content.

Like Vine and other short-video services, video is limited. This time to 15 seconds.
