Biography

Initially, most of the episodes featured the life stories of historical figures or present political or social leaders. After a few years, however, the show began producing episodes on figures from pop culture. This move away from purely intellectual subject matter has been criticized by some.[1] However, the original Wallace series also featured pop culture figures; in fact, the very first episode discussed the life of baseball icon Babe Ruth. In addition, the series has recently covered figures in the business and technology world, such as Sam Walton, founder of Wal-Mart, and Sergey Brin and Larry Page, founders of Google.
