In the Czech Republic, C&COM Advertising has been a full member of the AČRA-mk (Association of Czech Advertising Agencies and Marketing Communication) since 2000. Since 2002, the agency director Ing. Petr Linda has been a member of the Presidium of the Executive where he was re-elected by the membership base in 2005. The aim of the association’s activity is to increase the professional level of Czech advertising and other activities in the marketing community. Association activities are designed to coordinate and represent the common interests of its members, their representation to the relevant industry associations and government bodies, provide technical information, advisory services, and develop activities to promote a favorable image.

C&COM Advertising is a full member of a European network of independent agencies known as the E3 Network. E3 is now composed of 22 permanent members and 5 partner agencies. Until 2003, membership consisted of agencies from mostly EU countries, but in the last two years there has been an increase in new members. The new members include agencies from the so-called new European countries and also of members from the former Soviet Union. The E3 network maintains mutual partnership and mutual information exchange including cooperation with agencies from Canada and the U.S. - associated in the TAAN Network. The network recently started exploring the Asian market, and the first agency to join us is a partner from Singapore. Being a member of the Association has many advantages for our agency such as foreign contacts, use of association intranet, access to a library of case studies and research, exchange of know-how among agencies and more than exemplary international interagency cooperation for network clients. Another advantage of membership is the shared knowledge between agencies concerning global projects. Member agencies are able to consult each other as to their respective markets as well as to possible cultural differences that need to be taken into consideration when working on a project. In 2007, Ing. Petr Linda, director of the C&COM Advertising, was elected a member of the Presidium E3 Network.
