According to Adam Mosseri (head of Instagram), Instagram is not a photo-sharing app anymore. Mosseri posted a video to his Instagram and Twitter accounts stating that the company is moving into entertainment and video following the success of YouTube and TikTok.He explains some of the new changes Instagram will make, such as showing recommendations for topics users don't follow and making video more immersive with a full-screen experience.Video on Instagram is changingInstagram is constantly looking for new features to help users get the most from their experience. We are currently focusing on four areas: Video, Creators, Shopping, and Messaging. pic.twitter.com/ezFp4hfDpf Adam Mosseri - June 30, 2021Instagram's experiment with algorithmic additions in the main feed was recently reported. However, the idea of basing them on topics users can choose seems to be a novel one for the platform. While the app has had full-screen video experiences in the main feed for content uploaded to IGTV, Reels and Stories for a while, Mosseri said that they are now looking to embrace video more widely.Instagram is a clear message: It doesn't want to be seen as just a photo-sharing app as Mosseri suggests, but as an entertainment app that is driven by algorithms and videos. It is unclear at the moment how Instagram will accomplish this.
