Trade Me is a mass media platform that brings people together from different backgrounds and locations to buy, sell, travel, and engage in their communities. It has decentralized market power and provides equal access for all market participants regardless of size or location. This has increased communication, allowed for anonymity, and enabled trading across cultures, ages, and geography while improving access to information. Trade Me's ability to enable social change depends on three factors: the content it provides related to trading, jobs, vehicles, property, services, travel and communities; the influence and impact of that content on audiences; and its relationships with other institutions that provide complementary services.
