Lorem Ipsum is simply dummy text of the printing and typesetting industry. It has been the industry's standard dummy text since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting.
The text is derived from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This makes it over 2000 years old. The standard chunk of Lorem Ipsum used since the 1500s is reproduced for those interested.
Lorem Ipsum is useful because it has a more-or-less normal distribution of letters, making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy.
