The story
In May, 1980, a U.S. subsidiary of Cable America Inc., Cablecasting Ltd. bought up 80% of a cable company in the state of Dekalb Cablevision Inc., serving 16,000 households in De Kalb, Georgia.
Before SHAW Communications bought up these assets for $307,500,000 in 1992, Cablecasting Limited had 320,000 subscribers in the systems listed above. It was the fifth largest cable company in Canada.
After an asset swap between Shaw and Rogers Cable in 2001, most of the areas formerly served by Cablecasting are now held by Rogers Cable.
