History.
The Macbook was introduced by Apple in May 2006. It replaced the iBook and 12 inch PowerBook series of notebooks because Apple was switching all of their CPUs to Intel from Power PC's.
Apple upgrades, or makes the MacBook better, about every six months to two years. This makes them faster and more reliable.
In October 2008, Apple decided to make a MacBook housed in aluminum. It was pretty much the same as the one housed in plastic except that it was a little better and that it was housed in metal. In June 2009, during WWDC (Apple's big yearly gathering), this laptop was renamed the MacBook Pro 13 inch.
In 2011, Apple stopped the production of MacBooks. However, in 2015 Apple released 12-inch MacBook, with a smaller Retina display.
