Lorem Ipsum is essentially the typeset and printing industry's dummy text. Since an unidentified printer jumbled a galley of type to create a type specimen book in the 1500s, Lorem Ipsum has been the industry standard sham text. It is virtually intact, having withstood not just five centuries but also the transition to electronic typesetting. The introduction of Letraset sheets with sections from Lorem Ipsum in the 1960s and, more recently, the inclusion of Lorem Ipsum versions in desktop publishing programs like Aldus PageMaker contributed to its popularization.
