News Feed highlights information that includes profile changes, upcoming events, and birthdays, among other updates. The new layout, by contrast, created an alternative home page in which users saw a constantly updated list of their friends' Facebook activity. Originally, when users logged into Facebook, they were presented with a customizable version of their own profile.
On September 6, 2006, Ruchi Sanghvi announced a new home page feature called News Feed. Using a secret method (initially known as EdgeRank), Facebook selects a handful of updates to actually show users every time they visit their feed, out of an average of 1500 updates they can potentially receive. The news feed is the primary system through which users are exposed to content posted on the network.
