CBC has set the premiere date for Test the Nation: Watch Your Language, hosted by Wendy Mesley and Brent Bambury. The two-hour second edition of the interactive quiz show will air Sunday, September 9 in the 8-10 pm time slot.

Viewers will be encouraged to participate in online ‘mental gyms’ at CBC.ca/TestTheNation or with a scorecard, both sponsored by Quaker. The site will go live on September 8, and the scorecard will run in the National Post that day.

The CBC had originally planned to include an SMS/mobile participation component in the show, but it will now be postponed until future shows (January or March 2008). The change was due to technical concerns about the quality of graphic rendering on mobile devices, which could have skewed test results.

The on-air competitors consist of seven teams: word gamers; ad writers; English teachers; fraternities and sororities; comedians; romance novelists and celebrities. The celebs include Cathy Jones, Sheila McCarthy, Kim Stockwood, Patrick McKenna, Sook-Yin Lee, Russell Smith and Andrew Coyne.

The first edition of Test the Nation in March raked in 1.5 million viewers (724,000 in the A25-54 demo) against CTV’s Law & Order: CI and Amazing Race. About 200,000 people participated online.

The third installment of Test the Nation, with a world trivia focus, is on the sked for January.
