George Gallup died in 1984. Four years later, his family sold the firm for an undisclosed price to Selection Research, Incorporated (SRI), a research firm in Omaha, Nebraska. The family's involvement with the business continued; sons George Gallup Jr. and Alec Gallup kept their positions as co-chairmen and directors. George Gallup Jr. (1930–2011) established the nonprofit George H. Gallup Foundation as part of the acquisition agreement. SRI, founded in 1969 by the psychologist Don Clifton, focused on market research and personnel selection; it pioneered the use of talent-based structured psychological interviews. Acquiring the Gallup name gave SRI more credibility and higher response rates.
