Why do we use it?

It is a long established fact that a reader will be distracted by the
readable content of a page when looking at its layout. The point of
using Lorem Ipsum is that it has a more-or-less normal distribution of
letters, as opposed to using 'Content here, content here’, 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. Various versions have evolved over the years, sometimes by
accident, sometimes on purpose (injected humour and the like).

Where does it come from?

Contrary to popular belief, Lorem Ipsum is not simply random text. It
has roots in a piece of classical Latin literature from 45 BC, making
it over 2000 years old. Richard McClintock, a Latin professor at
Hampden-Sydney College in Virginia, looked up one of the more obscure
Latin words, consectetur, from a Lorem Ipsum passage, and going through
the cites of the word in classical literature, discovered the
undoubtable source. Lorem Ipsum comes 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 book is a treatise on the theory of
ethics, very popular during the Renaissance. The first line of Lorem
Ipsum, „Lorem ipsum dolor sit amet..”, comes from a line in section
1.10.32.

The standard chunk of Lorem Ipsum used since the 1500s is
reproduced below for those interested. Sections 1.10.32 and 1.10.33
from „de Finibus Bonorum et Malorum” by Cicero are also reproduced in
their exact original form, accompanied by English versions from the 1914
translation by H. Rackham.
