The Financial Post reports in its Friday edition two public-interest lobby groups are challenging a sales tactic employed by Shomi that limits the service's use to only existing cable or Internet subscribers of its co-owners, Rogers and Shaw. The Post's Christina Pellegrini writes the Public Interest Advocacy Centre and the Consumers' Association of Canada (PIAC-CAC) contend that Shomi, Rogers and Shaw have been in "clear violation of the prohibition against unjust discrimination and undue preference" since the streaming service became available last November. Despite Shomi's plans to eventually lift the restriction, PIAC wrote to the CRTC that the news unveiled Wednesday was short on key details -- such as a firm launch date and whether an active TV subscription is required -- and asked if the regulator still planned to render a decision specifically on whether tying Shomi to a specific Internet service has been violating the Telecommunications Act and the Broadcasting Act. Submissions are due Monday. Shomi's Jodi Cook said: "Shomi will be available OTT (over-the-top) to all Canadians through their Internet provider." Shomi, which has a growing library of 15,000 assets, costs $8.99 per month.
