The PowerBook (known as Macintosh PowerBook before 1997) is a line of Macintoshlaptopcomputers that was designed, manufactured and sold by Apple Computer, Inc. from 1991 to 2006. During its lifetime, the PowerBook went through several major revisions and redesigns, often being the first to incorporate features that would later become standard in competing laptops. The PowerBook line was targeted at the professional market, and received numerous awards, especially in the second half of its life, such as the 2001 Industrial Design Excellence Awards "Gold" status, and Engadget's 2005 "Laptop of the Year". In 1999, the line was supplemented by the low-end iBook range. The PowerBook and iBook lines were discontinued and replaced by the MacBook Pro and MacBook families respectively by 2006.
