Last week, Canadian networks revealed to the media and advertising community their fall television schedules. Canadian network programmers commit to shows they hope will be the newest hit in the U.S., while still maintaining their required commitment to Canadian content. Not an easy task. Rampant programming changes, time-period shifts, new series cancellations and mid-season launches continue to create a viewing environment that is as volatile as ever. So, like every year, it will be a revolving door of new shows, some that last a couple of weeks, some only a few episodes; and some even make it through to mid-season.
