The first major algorithm update was called the "Farmer Update." The goal of this core update was to devalue content farms, like Ezine.com. These websites promoted thin spammy content that provided little to no value. The publishers used this as a way to get backlinks to their blogs.
The most popular algorithm update that originated in 2011 and is still a key update is the Panda Update. This is not named after the furry Chinese bear, but rather it is named after Google engineer Navneet Panda.

The goal is to devalue these sites so the content is pushed further down in the results pages, the content becomes invisible.
