Just as the hockey season kicks off in Canada, a reality show featuring ice-rink competition has become an enormous ratings hit for the usually staid, government-supported Canadian Broadcasting Corp. (CBC). The show, Battle of the Blades , is a kind of Dancing With The Stars in which a Canadian figure skater is put together with a professional hockey player in a pairs competition. The first two shows of the series average 1.75 million viewers, according to BBM Nielsen -- one of the highest ratings yet for an original Canadian series, and nearly twice the average number of Canadian viewers who watched Hockey Night in Canada last season.
