TikTok is a social media platform for creating, sharing, and discovering short videos. It was launched in 2016 by the Chinese technology company ByteDance. Users can create videos ranging from 3 seconds to 10 minutes long, but the most common length is 15 seconds. The app allows users to get creative with their content using filters, stickers, voiceovers, sound effects, and background music. TikTok is notable for its personalized feeds of quirky short videos set to music and sound effects, which makes it addictive and engaging. The app has gained global popularity and is now available in more than 150 different markets. Despite its popularity, TikTok has faced concerns about privacy and inappropriate content. The app has a minimum user age of 13 years old, and in Ireland, the Digital Age of Consent has been set at 16 years old.
