Snapchat is a multimedia messaging app popular among younger demographics, known for its unique feature of sending photos and videos (snaps) that disappear after being viewed. Users can add filters, lenses, or various effects to their snaps and create Stories that compile snaps and last for 24 hours. The app also offers a Discover section for branded content and media stories. Snapchat emphasizes privacy and spontaneous, in-the-moment communication. It's particularly valued in digital marketing for reaching younger audiences with creative, time-sensitive content that leverages the platform's ephemeral nature.
