Chicago Public Media is paying $450,000 to buy Radio Arte, a low-power station programmed by and for Latino youth and operated by the National Museum of Mexican Art in Chicago. CPM also plans to buy programming from Radio Arte to add to its Vocalo service. “This is a natural partnership,” said Silvia Rivera, Vocalo’s managing director, whose career in public media began in 1998 after taking part in Radio Arte’s media training program. “This partnership between two youth-driven public radio stations builds on a collaborative history and their complementary community missions,” the new partners said in a June 22 press release. CPM will also sponsor museum activities and events as part of the arrangement.
