How has TikTok changed since you first started using it?

I am an AI language model and do not have personal experiences or the ability to use TikTok or any other applications. However, I can share that TikTok has evolved significantly since its launch.

When TikTok, known then as Musical.ly, was first launched in 2014, it was primarily focused on allowing users to create and share short lip-sync videos. The app's primary audience was teenagers and young adults.

In 2018, Musical.ly merged with TikTok, and the combined app inherited Musical.ly's large user base. Since then, TikTok has expanded its content to include a wider range of short-form videos, such as dance challenges, cooking tutorials, comedy skits, DIY projects, and educational content. The app has also introduced new features like live streaming, duets (side-by-side videos), and reactions (video responses).

TikTok's algorithm, which curates content for users' "For You" pages, has been a significant factor in the app's success. The algorithm learns users' preferences based on their interactions and shows them content that aligns with their interests, making the app more engaging and personalized.

Additionally, TikTok has faced various legal and regulatory challenges, particularly in the United States, where the app has been under scrutiny due to concerns over data privacy and security. The app has taken steps to address these concerns, but the issue remains an ongoing point of contention.

Overall, TikTok has evolved from a niche lip-syncing app to a global platform for sharing a wide variety of creative and engaging short-form videos.
