Instagram is gunning for YouTube with a plan to allow longer-form video, according to the owner of an influencer network whose clients have talked with the Facebook-owned company, as well as numerous media reports.

Allowing long video could help Instagram court social media stars and their millions of fans to use its platform as their primary online home, instead of relying on YouTube, where many have fewer followers. And when the users move, so will the marketers, meaning Facebook stands to gain advertising revenue at Google-owned YouTube's expense.
