KPBS will create an interactive newsroom for multimedia and multi-platform projects with a $2.5 million gift announced today. The donation came from Irwin Jacobs, co-founder and former chairman of Qualcomm, and his wife Joan, longtime supporters of the San Diego station. Right now reporters, writers, producers and support staff work throughout the building. “It was time we created a physical environment where all news and content producers can work collaboratively,” said Tom Karlo, KPBS general manager.
