TikTok has become one of the most popular social media platforms, attracting millions of users worldwide with its short videos. With 1.59 billion monthly active users as of 2025, it ranks fifth among global social networks, capturing particularly strong engagement from users aged 18-34 who comprise approximately 66% of its audience. The platform's success stems from its sophisticated algorithm that creates highly personalized content feeds, keeping users engaged for an average of 58 minutes daily. This extensive reach and deep engagement have made TikTok a powerful marketing channel, generating $23 billion in revenue in 2024 and becoming the first non-gaming app to exceed $6 billion in in-app purchase revenue.
