Comedy continues to snag the largest audiences for CBC, while it’s been hit-and-miss for the pubcaster’s realities, including Dragon’s Den, No Opportunity Wasted and Triple Sensation.

Season two of Dragon’s Den continued to grow its audience last week, nabbing 504,000 viewers Monday at 8 p.m. opposite CTV’s Dancing with the Stars. The third episode of the season saw Dragon’s Den up its numbers from its first two, which garnered 389,000 and 461,000, respectively.

The picture is not so rosy for the net’s other reality, No Opportunity Wasted, likely due in part to its tough timeslot on Wednesdays at 8:30 p.m., where it airs opposite the second half of CTV’s Private Practice. The show managed a soft 351,000 last week, down from the 450,000 that tuned in for its first episode.

NOW is preceded by Little Mosque on the Prairie, which hit 919,000 last week, up from 750,000.

Meanwhile, CBC rolled out the new half-hour reality series Who Do You Think You Are? to 440,000 viewers on Oct. 11, but couldn’t keep them, the number dropping to 235,000 a week later. The series by Barna-Alper Productions follows celebrities such as Chantal Kreviazuk and Don Cherry as they trace their family roots.

Garth Drabinsky’s three-part reality series Triple Sensation, about the nation-wide search for Canada’s most talented performers, ended its 3 x 120 run on Sunday with a season average of 313,000 viewers. Newmarket, ON native John-Michael Scapin was named the winner on the show.

Meanwhile, This Hour Has 22 Minutes slightly outperformed The Rick Mercer Report last week, garnering 686,000 viewers on Oct. 16, compared to 673,000 for Mercer. The comedies were followed by episode three of The Tudors, which remains a strong contender for CBC at 9 p.m., scoring 775,000 viewers.

Chris Haddock’s Intelligence continues to struggle, though it increased its audience last week to nearly 300,000 viewers, up from 221,000 for its first episode.
