The Miami Herald and Knight Ridder executives have closed Street Weekly, the free youth-oriented tabloid that was meant to engage young readers and compete directly with Miami New Times. Late Wednesday staff members were informally told that the issue appearing on Friday, January 7, would be the last. Human resources officials were scheduled to meet with staff on Thursday afternoon for a formal announcement. The Herald began publishing Street in 1999. Many daily newspapers publish weeklies in an effort to capture revenue in the lucrative “alternative” market, as well as to experiment with ways to lure younger readers.
