Leora Kornfeld is a digital media researcher and former radio personality. She was best known for hosting Realtime on CBC Stereo in the 1990s, which was billed as the first radio program in the world to integrate emerging Internet technologies such as e-mail and IRC into its program format.
Kornfeld got her start in radio at CITR-FM, the campus station at Vancouver's University of British Columbia where fellow disc jockeys included Terry McBride, founder of the Nettwerk label, former Globe and Mail music critic Chris Dafoe, CBC Radio commentator and digital marketing consultant Tod Maffin, and Vancouver Jazz Festival founder Robert Kerr. After graduating from UBC she went on to work at CFOX-FM, first as a technical operator during the 2-6 a.m. shift and then as the writer for the syndicated program The Rock Journal. Following her stint at CFOX she ventured into television writing at the CBC. Her first job there was on the short-lived late night teen series pilot 1. She then went on to work on the final season of Switchback and the inaugural season of Streetcents.
Kornfeld made the leap from CBC Television to CBC Radio, starting as a writer/producer and eventually as host of the music magazine program The Beat heard on CBC Radio 1 and Radio 2 in the early 90's, and continued her hosting duties at CBC on the programs Realtime (1994–1997) and Radiosonic (1997–1999). Realtime was merged in 1997 with David Wisdom's Night Lines into a new program called RadioSonic, and Kornfeld and Wisdom continued as cohosts of RadioSonic until 1999, at which time Kornfeld took a leave from CBC to pursue graduate studies in Media & Communications at Goldsmiths College, University of London.
She now limits her participation in broadcasting to occasionally providing guerilla journalist Nardwuar the Human Serviette with obscure facts about musicians, artists, and assorted celebrities, and has contributed DVD commentary for his 2006  and 2007  DVDs. She did, however, appear on CBC Radio 3 on March 17, 2007, during a special program to mark the end of the network's terrestrial simulcast on Radio Two.
Since 2008 Kornfeld has been a Research Associate at Harvard. Her work focuses on the new models of communication and new business structures enabled by digital, connected networks. Her published work includes cases on digital marketing in the music industry, politics in the age of social media, and how organizations such as Coca-Cola and Ford have pioneered new marketing strategies based on user-generated content.
