IGTV is a long-form video channel accessible from both a user’s IG profile and its own standalone app. Having launched in 2018, IGTV lets users create their own long-form videos and video series on Instagram. Users are able to post previews of their IGTV posts on their feeds to increase discoverability as well as to create series that are released regularly (weekly, monthly, etc.)..
Verified users are permitted to post IGTV videos up to an hour long with other accounts able to post videos up to 10 mins long. Instagram recently announced that eventually, the app will permit unlimited lengths for all users.
