List has been transferred to lead several newspapers in western Iowa.
He began his new duties this week.
Pruett will oversee the day-to-day activities of all three properties.
Lynne Llewellyn will remain as general manager of The Times, and Daryl Taylor will continue as general manager at the Banner Graphic.
"Since I will be living in Iowa, it was necessary to have someone here in Indiana who I could rely on to handle the day-to-day issues of running the newspapers," List said. "I'm very confident in Chris as that leader and know that Daryl and Lynne will continue to strive to give our readers all the news happening in their communities."
Pruett said he's looking forward to his new role with Rust Communications.
"I appreciate Randy's confidence and allowing me the opportunity to help manage the other two Indiana properties," Pruett said. "Lynne and Daryl have a lot of experience at their papers and do a good job."
Pruett was named general manager of the Greene County Daily World (GCDW) and The Shopper when Rust Communications purchased the GCDW in January 2003, and The Shopper in March 2003.
He's also the editor of the GCDW.
"One of the reasons I accepted the promotion is because of the great staff I have in Linton. Without their help, there's no way I'd be able to take on these new responsibilities," Pruett stressed.
Pruett came to Greene County in 1983 to serve as sports editor of the former Linton Daily Citizen (LDC).
He also served as editor during a portion of that time.
He moved on to the Terre Haute Tribune-Star in July 1990, and was assistant sports editor, until moving back to Greene County in February 1998, when the LDC was purchased by Thomson Newspapers, the same company that owned the Terre Haute paper at the time.
He has served as editor and later general manager since that time.
Pruett and his wife, Debbie, have been married for 27-and-a-half years and they have one daughter, Rachael, a graduate student at Ball State University.
List moved to Greencastle in February 1999 as publisher when Rust Communications purchased the Banner Graphic, and he took over at The Brazil Times when it was purchased by Rust in 2001.
In 2010, he was promoted to regional vice president of Rust Communications and will oversee 11 newspapers and two shoppers in Iowa, one in Nebraska, and one in Idaho, in addition to his three Indiana properties.
List and his family will relocate to Iowa.
List started his career for his hometown paper in Yankton, S.D., in 1974, as a proofreader in the advertising department.
"I've also held various positions over my career in South Dakota, Nebraska, Minnesota and California, before moving to the Journal-Review in Crawfordsville and then Greencastle," List said.
List and his wife, Kathleen, have four children together, including daughter Emilie, her husband Mike, and granddaughter Stella, Fishers, Ind.; his son Phil, who is a lawyer in Indianapolis; daughter Katie and son Kevin, who live at home and attend Greencastle schools.
Kathleen is the administrative coordinator for libraries at DePauw University.
Llewellyn came to The Times in 1993 as a sales representative and was then promoted to prepress manager.
"I soon took on advertising manager duties when our advertising manager retired," she said. "When Rust bought us, I was promoted to general manager.
"Randy will be missed in Brazil. I learned from him often. I know that his new staff will learn to appreciate his expertise as I did."
