The online platform that started as a photo-sharing site but later expanded into a social media platform is Instagram. Launched in 2010, Instagram was initially designed for users to share photos with social connectivity. Over time, it introduced new features like Stories, direct messaging, and IGTV, transforming it into a comprehensive social media platform. Today, Instagram boasts billions of users who engage not only with photo content but also with video, shopping, and various influencer marketing opportunities, significantly impacting digital communication and branding.
