Smith's son David D. Smith began taking a more active role in the company in the 1980s. In 1985, the Chesapeake Television Corporation changed its name to the Sinclair Broadcast Group. In 1990, David Smith and his three brothers bought their parents' remaining stock and went on a buying spree that eventually made it one of the largest station owners in the country, through the purchases of groups such as Act III Broadcasting (in 1995) and River City Broadcasting (in 1996).
