Christopher S. Yoo is a professor of Law, Communication, and Computer and Information Science at the University of Pennsylvania Law School, and founding director of the Center for Technology, Innovation, and Competition. He is well known for his work on technology law, media law and copyright, in which field he is among the most frequently cited authors. He has written extensively on the regulation of the Internet, the economics of copyright and imperfect competition. Yoo is one of the most vocal skeptics of network neutrality, favoring an alternative approach that he calls "network diversity." He has also studied the history of the unitary executive in the United States.
Education and early career
Professor Yoo got his undergraduate education at Harvard University (cum laude), where he was a National Merit Scholar. He then moved to the Anderson School of Management at UCLA, where he completed the MBA program, and in 1995 he graduated from Northwestern University School of Law (magna cum laude). Following his graduation he clerked for Judge Arthur Raymond Randolph of the United States Court of Appeals and for Supreme Court justice Anthony Kennedy. He has also practiced law with Hogan & Hartson in Washington, DC.
From 1999 to 2007, Yoo was a professor at Vanderbilt University Law School. From 2005 to 2007, Yoo directed Vanderbilt's Technology and Entertainment Law Program. During the 2006-07 school year, he was also a visiting professor at the University of Pennsylvania Law School. He accepted an appointment as a full professor of law at Penn beginning in 2007. Yoo also has a secondary appointment at the Annenberg School for Communication at the University of Pennsylvania, and as of 2010 at the School of Engineering and Applied Science. Since 2005 Yoo has been called ten times to testify before Congress, the Federal Communications Commission, and the Federal Trade Commission. He is a member of the American Law and Economics Association, the Federal Communications Bar Association and the National Asian Pacific American Bar Association.
Cristopher Yoo came under scrutiny in 2014 while testifying in favor of Comcast's $45 billion merger with Time Warner Cable. During testimony, Yoo claimed that the merger likely would not hurt customers. David Cohen, a Comcast executive, is chairman of the trustees of the University of Pennsylvania where Christopher Yoo teaches, which is a potential conflict of interest for Yoo. Additionally, Yoo serves as the founding director of the Center for Technology, Innovation and Competition which performs independent research aimed to shape the way legislators think about technology policy.  This organization has also been criticized for existing primarily to further the agenda of large technology corporations. Among the list of companies that donate to the organization are: AT&T, Comcast, Facebook, Google, Intel, Microsoft, Qualcomm, Charter Communications, and Verizon.
