DAYTON — Julia Wallace has been named market vice president of Cox Media Group Ohio and will oversee the company’s newspaper, television and radio properties in the Dayton and Louisville markets.

Wallace, 54, served as editor of the Cox Media Group-owned The Atlanta Journal-Constitution for nearly nine years until January 2011, when she joined CMG Ohio as senior vice president of news and programming. In that position, Wallace was responsible the content and newsgathering operations of WHIO-TV, Cox Radio and Cox Ohio Publishing, which includes the Dayton Daily News, the Springfield News-Sun, daily and weekly papers in Northern Cincinnati and their websites.

Wallace will oversee the business operations of CMG Ohio in addition to the content and newsgathering operations.

She succeeds Alex Taylor, who was promoted to Cox Media Group executive vice president based in Atlanta earlier this year.

Taylor said Wallace is “a proven leader” and “one of Cox’s most forward-thinking professionals. She understands and reflects our enduring corporate values.”
