A national radio report this weekend revealing that hyperlocal content provider Journatic used false bylines in several stories that ran in TribLocal online has prompted an investigation by the Chicago Tribune. Journatic, brought in to run part of the Tribune's community news operation, has acknowledged its mistake and said it would discontinue the practice.

"This American Life," which is produced by Chicago public radio station WBEZ-FM, included a 23-minute segment focusing on Journatic's use of low-paid Filipino freelancers to cull and format information for stories, some of which were published under aliases.
