The Colonial Williamsburg Foundation says revenue at the historic area increased in 2013 and donor support significantly outpaced the previous year. Officials say ticket revenue increased by about $370,000, or 2 percent. That’s because it saw higher sales of single-day, multiday and annual passes. The Richmond Times-Dispatch report that the foundation also announced Thursday that it will begin looking for someone to succeed CEO Colin Campbell. Officials also said gift commitments in 2013 totaled $74.7 million, a 17 percent increase over 2012. Its endowment ended 2013 with a value of $780 million, a $45 million increase over the previous year. The Colonial Williamsburg Foundation operates and maintains the preserved 18th century site as an educational and tourist venue.
