Instagram's Short-Form Video Bet: The Strategic Rationale for Reels

Instagram launched Reels, a format for short, full-screen vertical videos with music and editing tools, and has kept putting significant resources into it. As a product manager, explain the reasoning behind that investment from the point of view of Instagram's users, its creators and Meta's business. ```hint Follow the time spent Ask where people, especially younger ones, were spending their phone time around 2019 and 2020, what Instagram's business depends on, and how Instagram reacted the last time a rival app's format took off. ``` ### Clarifying Questions - Should I explain the decision as it looked at launch in 2020, or also why Instagram kept expanding the investment in later years? - Should the answer stay on Instagram, or include Meta-wide reasons such as bringing the format to Facebook and improving recommendation systems? - Do you want my own view on whether it was the right call, or an explanation of the reasoning only? ### What a Strong Answer Covers - The competitive and behavioral context: a fast-growing short-video rival, the shift of younger users' attention, and how full-screen video changed what people expect from a feed - Reasons on each side of the platform (viewers, creators and advertisers) and how they reinforce each other - The shift from content posted by accounts you follow to recommended content, and why that matters for engagement and discovery - Why building inside Instagram beat a standalone app, an acquisition or doing nothing - Costs and risks, including cannibalizing feed and Stories, slower early monetization and alienating long-time users, plus how you would judge whether the investment paid off ### Follow-up Questions - Reels earned less per minute than feed posts at first. How would you have justified continuing to invest while that gap lasted? - Some long-time users complained that Instagram was turning into a video app. How would you balance Reels growth against that core audience? - If you ran Meta's strategy, would you have launched short video as a separate app instead? Why or why not?
