The Globe and Mail reports in its Saturday edition that pronounced "Da Zone," Dazn is a U.K.-based sports-streaming product that costs $20 a month. The Globe's Andrew Willis writes that newly launched Dazn will let subscribers watch every NFL game this season, anywhere they have Internet access. Upstarts such as Dazn, which is backed by billionaire industrialist Len Blavatnik, are a nightmare for BCE, which paid up in June for the TV rights to NFL games in Canada, along with Rogers Communications and the television networks that invest heavily in sports programming. These broadcasters made massive financial commitments to football, hockey, basketball, even curling. They are trying to preserve ties with an audience that still shows up faithfully for live sports and hang onto advertisers that want to reach beer-drinking, car-buying consumers. Sports are shaping up to be a poor investment. If Dazn's recent Canadian premiere is any indication, the bugs are out of the system, as streamed games matched the quality seen on any TV network. If Dazn's experience in Japan and Germany is any guide, two-thirds of subscribers will watch NFL football and other streamed sports on their TV.
