NBC Universal is launching the Web site DiverseCityNBC.com as part of its program to expand opportunities for performers from different ethnic and racial backgrounds. Marc Hirschfeld, executive VP of casting for NBC Entertainment, made the announcement Wednesday.

NBCU will offer information on performers, shows, diversity issues and job and internship listings on the free site. Readers can ask questions and notify the company about upcoming events and performances. The site will also be a resource for agents, managers and casting executives to locate unsigned talent.

“As the site expands, we hope to become a one-stop shop for listings of diversity events produced not only by NBC Universal but the Hollywood creative community and events nationwide,” Mr. Hirschfeld said in a statement.

Damona Resnick, producer of NBCU’s talent diversity initiative, will maintain the site. Last fall Ms. Resnick produced “Stand-Up for Diversity” open calls and showcases in Chicago; Atlanta; Miami; Austin, Texas; and San Francisco. As a result of those showcases, stand-up comics Marvin Michaels and Brent Weinbach were signed to one-year holding deals with NBC Universal Television.
