What Does Facebook Timeline Mean?
Facebook Timeline is a social media feature introduced by Facebook in September 2011 and rolled out to all users in February 2012. Timeline combines a user's Facebook Wall and Profile into one page, creating a more visually holistic profile. It includes reverse-chronological details, by year, of a user's Facebook history with key life points, including birthdays, weddings and other major events.
Timeline reorganizes all stored user information for display, rather than archival. In previous Facebook incarnations, it was more difficult or impossible to view outdated events, photos and comments.
Techopedia Explains Facebook Timeline
Initially, Timeline was optional, but in February 2012, Facebook began rolling out the change to all users. As with all Facebook changes, Timeline raised user privacy concerns, but Facebook claims the Timeline implementation does not affect privacy settings and that users maintain control over who sees their updates, photos and other entries.
Timeline also includes integration with Timeline Apps, which allows Facebook users to post activities on other apps. For example, a Pinterest user might give Facebook permission to post his or her Pinterest activities to the Facebook news feed, allowing friends to view Pinterest updates.
