Quebecor, Videotron’s Canadian cable operation, has announced that it expects to more than double the number of digital subscribers over the next two years thanks to the launch of a new video-on-demand (VoD) service. The company launched VoD to 17,000 customers in Montreal yesterday; the service will be rolled out across the rest of the province by August. At the end of last year the company claimed 182,000 digital cable customers, a figure it anticipates will rise to 400,000 by end 2004.
