This document discusses competition policy and regulation in the digital age in South Africa. It outlines the competition policy framework, including the Competition Commission Act and Electronic Communications Act. The Competition Commission and ICASA both have jurisdiction over competition matters in telecommunications, with the Commission addressing ex post issues and ICASA ex ante regulation. A precedent case found that the Competition Act applies to all economic activity, including in regulated sectors like telecoms. ICASA regulates mobile interconnection rates. While concurrent jurisdiction has generally been effective, some areas like broadcasting remain dominated by incumbents. Ongoing improvement is needed in competition and economic regulation.
