Markham Cho Erickson, a partner in Steptoe’s Washington office, has been involved in the practice of telecommunications and new media law for more than two decades, during which time he has played an integral role in the drafting and negotiating of many of the federal laws that govern communications, technology, and the use of the Internet.  He focuses on complex legal and policy matters before the federal government, state governments, and international deliberative organizations.  His clients include leading television programmers, Internet companies, online video distributors, non-profit organizations, start-up technology companies, and Indian tribes.

Mr. Erickson frequently advocates on behalf of his clients before the Federal Communications Commission, the Department of Justice, the Federal Trade Commission, and the US Congress.  He regularly represents clients in the prosecution and defense of regulatory complaints, rulemakings, and reviews of mergers.  He has challenged and defended agency actions before federal appellate courts. 

Mr. Erickson also serves as general counsel to The Internet Association, a trade association that represents 24 of the world’s leading Internet companies, including Google,, Facebook, eBay, Expedia, and Salesforce.  In this capacity, he counsels the organization on the leading legal and policy issues relating to the Internet sector and represents the organization in regulatory proceedings and before federal courts.

In addition, Mr. Erickson served as lead counsel to a coalition of Internet and technology firms that helped conceive and develop network neutrality regulations at the Federal Communications Commission, as well as in subsequent litigation before the US Court of Appeals for the District of Columbia Circuit.

Mr. Erickson has been quoted extensively and appeared in the media on various laws and issues relating to Internet and communication platforms.  He recently authored an article for The Federal Lawyer titled “Carcieri v. Salazar:  The Supreme Court’s Definition of ‘Now’ Creates Uncertainty for Indian Tribes.”  In addition, Mr. Erickson has taught classes on Internet-related issues at Stanford Law School and Georgetown University Law Center.

In May 2014, the Korean Minister of Science, ICT, and Future Planning appointed Mr. Erickson to serve as a legal mentor to the Korea Innovation Center, where he provides counsel to Korean start-ups and small-and-medium sized-businesses entering the US marketplace in the technology sector.
