Welcome to IGTV
… we have two big announcements to share. First, Instagram is now a global community of one billion! Since our launch in 2010, we’ve watched with amazement as the community has flourished and grown. This is a major accomplishment — so from all of us at Instagram, thank you!
Second, we’re announcing our most exciting feature to date: IGTV, a new app for watching long-form, vertical video from your favorite Instagram creators, like LaurDIY posting her newest project or King Bach sharing his latest comedy skit. While there’s a stand-alone IGTV app, you’ll also be able to watch from within the Instagram app so the entire community of one billion can use it from the very start.
IGTV is different in a few ways. First, it’s built for how you actually use your phone, so videos are full screen and vertical. Also, unlike on Instagram, videos aren’t limited to one minute. Instead, each video can be up to an hour long.
Also like TV, IGTV has channels. But, in IGTV, the creators are the channels. When you follow a creator on Instagram, their IGTV channel will show up for you to watch. Anyone can be a creator — you can upload your own IGTV videos in the app or on the web to start your own channel.
