Instagram is a social media platform that allows users to share photos and videos with their followers. The app was launched in 2010 by Kevin Systrom and Mike Krieger, who later sold it to Facebook for $1 billion.

To use Instagram, users create an account and upload their photos and videos using the mobile app or website. The images are then edited with a variety of filters, effects, and text overlays before being shared with friends and followers.

Instagram has had a significant impact on society, particularly in the realm of self-expression and community building. However, it has also raised concerns about mental health, cyberbullying, and the spread of misinformation.

Some of the popular features of Instagram include: - Filters: A wide range of filters that can be applied to photos and videos. - Effects: Additional effects such as glitter, boomerang, and square filters. - Stories: A feature that allows users to share ephemeral content with their followers.
