This artifact represents the development of one of Canada’s earliest commercial cable television systems because of Edwin R. Jarmain. In 1952, he successfully established an experimental cable operation in London, Ontario. He increased reliable access to over-the-air television by erecting a large rhombic antenna, and then transmitting—via cable. The rhombic antenna could pull down a stronger signal and provide a much more reliable television service. By 1974, service had expanded to 100,000 homes in Ontario, prompting Jarmain and his sons to go public as Canadian Cablesystems Inc. The company was bought out by Rogers Communications in 1979. In 2011, Jarmain was inducted into Canada's Telecommunications Hall of Fame as “the acknowledged father and pioneer of cable television in Canada.” L’objet représente le développement d’un des plus jeunes systèmes de télévision a câble au Canada grâce Edwin R. Jarmain. En 1952 il a établi un système prototype d'opération de câble à London, Ontario. Il a augmenté l’accès à la télévision en directe en construisant une antenne rhombique et en transmissent via câble. L'antenne pouvait tirer un signal plus fiable qui était plus fort et favorable pour les services de télévision. En 1974 le service a grossi à 100,000 maisons et Jarmain a pris la décision d'aller public avec le nom Canadian Cablesystems Inc. La compagnie a été achetée par Rogers Communications en 1979. En 2011 Jarmain a été intronisée au Temple de la Renommée pour les Télécommunications du Canada et a été reconnu comme le père et pionnier de la télévision a câble au Canada.
