Cityview, a weekly alternative newspaper in Des Moines for 25 years, will become a glossy monthly magazine with its Aug. 11 issue, Shane Goodman, owner of Big Green Umbrella Media, wrote in the paper today. Goodman wrote that readers want more of the paper’s alternative style of reporting, but that advertisers’ needs are changing. “They want glossy paper stock. They want to reach higher-income demographics. … And they don’t see the need to advertise on a weekly basis like they once did. With advertising as our sole source of revenue, we need to do all we can to accommodate these needs, or we won’t survive the next 25 years.”
