Revision3: PC Magazine’s Jim Louderback is jumping ship and sides, moving to Revision3 as CEO, according to NewTeeVee. Louderback was editor in chief for PC mag and editorial director for the Consumer/Small Business group at Ziff Davis Media. Louderback’s resume includes the launch programming for TechTV and managing ZD’s IPTV shows; the video background should come in handy. The hiring allows co-founder Jay Adelson to give up the CEO spot and focus on his other CEO job at Digg. Revision3 picked up $8 million in funding last month.
