The HDTV channels, which will now be 25 percent owned by the Torstar empire, sell a fine blend of niche entertainment. Much of it appeals to the intellect. All the channels are available only by subscription. The most broadly based of the quartet of HDTV signals is Oasis HD. It appears to be a family quality nature-oriented channel. The charming video from YouTube above, which is embedded on Oasis HD’s website, tells the story of a friendship between an elephant and a sheep. The channel eqed is proudly brainy. Eqed boasts the motto “Ït’s smart in here.” HIFI is a highbrow music and arts service. Finally, radX features risk, adventure and danger. Some may wonder what a relentlessly populist media giant like Torstar might like do with these rather narrowly-defined properties.
