Social media outlets differ from traditional media (e.g., magazines, newspapers, TV broadcasting, and radio broadcasting) in many ways, including quality,[6] reach, frequency, usability, immediacy, and permanence.[7] Additionally, social media outlets operate in a dialogic transmission system (many sources to many receivers) while traditional media outlets operate under a mono-logic transmission model (one source to many receivers). For example, a newspaper is delivered to many subscribers and a radio station broadcasts the same programs to an entire city.[8]
Some of the most popular social media websites, with over 100 million registered users, include Facebook (and its associated Facebook Messenger), TikTok, WeChat, Instagram, QZone, Weibo, Twitter, Tumblr, Baidu Tieba and LinkedIn.
