The Commercial Business Users Constituency (also known as the Business Constituency, or BC) represents the position and interests of small, medium, large and multinational enterprises as DNS and Internet Users to ICANN. The Constituency has over 50 members, but extends association membership to over 50,000 members and indirectly to over 1.5 million; 90% belong to small and medium enterprises (SMEs). It is one of the Constituencies under the Commercial Stakeholders Group (CSG) in the Non-Contracted Parties House under ICANN's GNSO. It was set forth by the ICANN Bylaws.
The main objective of the Business Constituency is to ensure the full representation of the views and interests of the Internet's commercial community, as ICANN policies should be consistent in maintaining a secure, stable and reliable Internet in conjunction with business development. It is important that they promote consumer confidence through participation in a common forum of both suppliers and users.
The Business Constituency has an Executive Committee designated to administer, supervise and coordinate its activities and positions to accomplish its mission and effectively represent its members to the ICANN Board.
The Constituency's responsibilities include:
- Election of two representatives, from different geographical regions, to the GNSO to discuss the Constituency's position regarding domain name policy issues.
- Evaluation of the qualification of a member based on the BC charter, undergone by the Constituency's Credentials Committee. David Fares, Mike O'Connor & Martin Sutton are members of the Credentials Committee.
- Appointment of two members to ICANN's Nominating Committee to represent small and large business. Waudo Siganga was appointed for small business in 2012 and 2013; Sarah Deutsch and Ron Andruff was appointed for large business were appointed for 2012 and 2013, respectively.

On New gTLDs
At ICANN 42 in Dakar, CBUC Chair, Steve DelBianco outlined 4 standing issues that the CBUC had with the current new gTLD Applicant Guidebook. These points were later picked up by TLD critics, including ANA and CRIDO, and are likely to influence a December 8th U.S. Senate hearing on new TLDs. Those 4 points are:
- Applications for gTLD IDNs- the value of gTLD IDNs was stressed by the CBUC, but they pointed out that ICANN had yet to recognize or publicize this exciting development for the global Internet.
- Trademark Protection- While there are 3 trademark mechanisms in place, one of them, the Trademark Claims Notice Service, can be turned off the day after Sunrise.
- Registrar Code of Conduct- A new Registry agreement was developed for the new gTLD program, but ICANN neglected to do something similar for registrars.
In August, 2012, 3 of ICANN's Constituencies (ALAC, GNSO Business Constituency, GNSO Intellectual Property Constituency) sent a letter to the organization complaining that the organization held its renewal talks with Verisign behind closed doors and the result is that there are no Thick Whois requirements for the .com TLD.
