On February 7, 1965, at 10:42 a.m., WVIZ signed on the air for the first time, broadcasting the word “THINK” from its first home, Max Hayes Trade School in Cleveland. The new WVIZ broadcast 50 hours a week—weekdays from 8:30 a.m. to 3 p.m. and 6 p.m. to 10 p.m. and on Sundays from 3 p.m. to 10 p.m. WVIZ became the 100th public television station in the nation.

In the early 1960s, Betty Cope, then a director at WEWS-TV 5, began working with a community group interested in activating educational television on Channel 25 for the Greater Cleveland area. In 1963, thanks to start-up grants from The Cleveland Foundation and the Educational Television Association for Metropolitan Cleveland, matched by a United States Department of Health, Education and Welfare grant in 1964, educational television in Northeast Ohio was becoming a reality.

Cope was WVIZ’s first general manager, and, in 1972, she was named president of the association that held the station’s license. Commonly called Channel 25, WVIZ was a member of National Educational Television (NET), which later became the Public Broadcasting Service (PBS) in 1970. The broadcast station officially changed its name to WVIZ/PBS in 1999.

Jerry Wareham became the station’s chief executive officer after Cope retired in 1993. Currently, Wareham is the CEO of ideastream, created in 2001, when WVIZ/PBS and 90.3 WCPN, an NPR member station, joined together to “strengthen our communities” and harness the power of multiple media. The growth continued and today ideastream is a nonprofit organization that applies the power of media to education, culture and citizenship. It includes WVIZ/PBS, 90.3 WCPN, WCLV 104.9 Classical, educational and public service cable channels, broadband interactive video distance learning and web and other interactive media, as well as a community engagement platform—Civic Commons.

WVIZ/PBS is now on 24/7 and includes four digital channels—WVIZ/PBS HD, WVIZ/PBS Create, WVIZ/PBS World and The Ohio Channel—as well as video on demand at video.ideastream.org. WVIZ/PBS ideastream Education builds upon WVIZ’s rich heritage of educational training programs by offering a variety of in-person, online and distance learning opportunities throughout the year, as well as managing the SMART Consortium (Science and Math Achievement Required for Tomorrow), a professional development program for teachers in Northeast Ohio’s school systems.

WVIZ/PBS ideastream is located in the Idea Center at Playhouse Square - 1375 Euclid Avenue, Cleveland, Ohio, 44115, and on the web at www.wviz.org
