On this episode of CEO EXCHANGE, taped at The Wharton School of the University of Pennsylvania in Philadelphia, we'll explore the rapidly changing world of MULTIMEDIA IN THE DIGITAL AGE. Meet two CEOs who have arrived at this crossroads from two different directions: cable television and publishing. Brian Roberts heads Comcast Corporation, the #1 cable provider in the country, which is now expanding rapidly into video-on-demand, Internet and telephone services. Terry McGraw leads The McGraw-Hill Companies, which are now placing far less emphasis on traditional publishing media in favor of textbooks, educational testing products and global financial services. Two CEOs, both running businesses founded by their families, on the cutting edge of the communications revolution.
