Trinity Media Group (Pty) Ltd was founded in October 2005 by Mark-John Cartmell. The company grew in leaps and bounds into one of South Africa 's leading media companies, known as ‘publishers of discerning quality’.

Based in Parklands, Johannesburg, Trinity Media Group embodies strong Christian values in all aspects of media communications and delivery. Although not publishers of religious titles, the core value system carried throughout Trinity Media Group's day-to-day business functions are strongly focused on maintaining a high level of moral integrity.

Publisher Mark-John Cartmell has been publishing magazines and hardcover books for over 10 years. Many well know South African titles such as Southern Sun Equinox and Sun International Nedbank Million Dollar Golf Challenge were conceived by Mark-John Cartmell.

After a decade of associated publishing, Mark-John Cartmell founded the Trinity Media Group, with the primary vision and dream of building a media company that produces publications of discerning quality.

Trinity Media Group offers a one-stop publishing solution, and publishes a wide spectrum of titles, ranging from corporate to retail, and from property titles to sports magazines. Publication in the Trinity Media Group stable include: SuperSport World of Champions; South African Sport Hall of Fame; 2010 Hotel and Leisure Guide; SQ; and The Pharmacist’s Information Guide.

The company has since closed down.
