2009: The Tieba Business Unit is established on August 10; the "World of Warcraft Bar" becomes the platform's largest bar amid the game's popularity, and a July post there ("Jia Junpeng, your mother is calling you home for dinner") draws roughly 390,000 views and more than 17,000 replies within six hours.

Baidu Tieba: What Is It?

Baidu Tieba is a free, topic-based online forum operated by Baidu, Inc. Users search for a subject of interest, and if a corresponding forum ("bar") does not already exist, the system lets them create one. It has been described as structurally similar to Reddit, with individual bars functioning much like subreddits.

Each bar can have up to three "bar masters," thirty vice-masters, and ten video-masters, all unpaid volunteers who set bar-specific rules and moderate content; Baidu staff can remove moderators at their discretion. Users can post text, images, polls, and video, but cannot edit a post once published, though they may delete their own posts or delete others' comments on their own posts. Bars ranked in the platform's top 500 receive a dedicated photo album, and each bar has 2GB of allotted video storage.

Baidu Tieba is used by general internet users pursuing hobby and interest discussions, by fan communities organizing around celebrities or media franchises, and, since 2013, by verified enterprise and institutional accounts using the "Official Bar" program for brand communication. The platform has also hosted consumer-to-consumer exchanges, drawing comparisons to Craigslist.

Baidu Tieba: Disambiguation

Baidu Tieba should not be confused with the following entities:

Reddit: An independently operated American discussion-forum platform that launched in 2008, five years after Baidu Tieba, and has been separately listed on Nasdaq (RDDT) since March 2024; Baidu Tieba remains a Baidu-owned product rather than an independent company.
Sina Weibo Super Topics (微博超话): A fan-community feature launched by Sina Weibo in June 2016 that drew much of Baidu Tieba's celebrity-fandom user base; it is a feature of a separate company's product, not a Baidu Tieba spinoff.
Zhihu (知乎): A separate Chinese question-and-answer community that drew away more discussion- and knowledge-oriented users from Baidu Tieba; Baidu holds a minority investment in Zhihu, but it operates as an independent company.
Baidu Baike (百度百科) and Baidu Zhidao (百度知道): Sister Baidu products structured around encyclopedia entries and question-and-answer content respectively, rather than Baidu Tieba's open, topic-based discussion-forum format.
Baidu Tieba overseas editions: Former localized Vietnamese, Brazilian Portuguese, and Thai versions of the platform, which had ceased operating by March 2019 and are not part of the current active service.
