The Canada Media Fund has had a good run of late rewarding broadcasters for airing first-run Canadian dramas like Rookie Blue, Flashpoint and Arctic Air in primetime.

Possibly too much success?

The public/industry fund on Thursday unveiled its latest so-called factor weights to calculate broadcaster performance envelopes from its 2012-2013 program guidelines.

And the new changes include the CMF tweaking the “audience success – original first run” factor to now apply to all genres, including children’s and youth and documentary fare.

The aim is to dangle a carrot in front of broadcasters to encourage “the creation of original content in these genres,” the industry fund said in a statement.

The modification is timely: The Profile 2011: An Economic Report on the Screen-Based Production Industry in Canada report released earlier this week revealed production volume for one-hour dramas was up last year, but production expenditures for TV movies and miniseries, kids and youth programming and documentaries was down.

As part of a second modification, the “digital media investment” factor is being bumped up from 5% to 10% to encourage the production of more convergent media projects.

To accommodate the latest factor weight changes, the CMF will reduce the existing “above-threshold licensing” factor, which gives broadcasters credit for eligible licences to fund supported projects that exceed established thresholds for program genres.

So the above-threshold factor for French-language broadcasters will fall to 5%, from 10%, and be scrapped altogether for English-language broadcasters’ performance envelope calculations.
