The Chicago Tribune Media Group, the Tribune Co. division that includes the Chicago Tribune, on Wednesday announced the promotion of newsroom executives Joycelyn Winnecke and Jane Hirt.

Chicago Tribune Editor Gerould Kern, a senior vice president, said in a memo to staff that Associate Editor Winnecke and Managing Editor Hirt each are adding the title of vice president after 22 months in their current posts in recognition of “their exceptional accomplishments and growing responsibility for the company.”

Each woman is taking on added duties, Kern noted, crediting the two with working together to help make the Chicago Tribune newsroom “a fully integrated operation supporting digital” along with working to increase collaboration with Tribune Co.’s WGN-Ch. 9, WGN-AM 720 and CLTV.

Winnecke is chief liaison between editorial, advertising and marketing on developing new revenue streams through Chicago Tribune Media Group content initiatives, special events and programs such as the recently launched Trib Nation consumer outreach project.

Kern said Winnecke also will work with him on projects involving other Tribune Co. properties, including its Chicago broadcast outlets, and will continue to oversee the company’s Media on Demand program, which has produced multimedia content for the Chicago Tribune and others inside Tribune Co. since February 2009.

Hirt has taken on increased responsibility for the Chicago Tribune day-to-day newsroom operations of late, according to Kern, who indicated he has become more involved in strategic development for the newspaper and other Tribune Co. publications.

A veteran of 17 years with the Tribune, Hirt played a leading role in launching and directing the company’s commuter tabloid RedEye as editor for its first six years before Kern named her the Chicago Tribune’s managing editor in August 2008, which is also when Winnecke was appointed associate editor.

Before helping launch RedEye, Hirt worked on the sports and national copy desks and was the Tribune’s foreign-national copy desk chief.

Winnecke was managing editor of the Chicago Sun-Times before joining the Tribune as associate managing editor for national news in 2002 to oversee what was then the paper’s five national bureaus, including Washington D.C.

“Two years ago in August, I asked Jane and Joyce to take on newsroom leadership roles at a transformative moment for the Chicago Tribune,” Kern wrote. “They responded with courage, creativity, grace and good humor.”
