While Walt led the creative side, Roy guided the business side and finances. Together Roy and Walt founded Disney Studios as brothers, but Walt later bought out most of Roy's share in 1929 so, unlike Max and Dave Fleischer of rival Fleischer Studios, Roy was not a co-producer. However, Roy was an equal partner in all facets of the production company.
Roy became the company's first CEO in 1929, although the official title was not given to him until 1966. He also shared the role of chairman of the board with Walt from 1945. In 1960, Walt dropped the chairman title so he could focus more on the creative aspects of the company. After Walt's death in 1966, Roy postponed his retirement to oversee construction of what was then known as Disney World. He later renamed it Walt Disney World as a tribute to his brother. Roy became the president of Walt Disney Productions from December 15, 1966, until 1968.
