This week on our encore Summer Series, we explore #1 Brands. We'll look at popular categories and identify the runaway best-selling brands, and analyze why they are #1. The best selling car in Canada has been on top for 15 years. Know what it is? Bet you can't guess the #1 pharmaceutical drug in Canada - it's completely different from the top one in the U.S. Most re-tweeted Tweet of all time? Number one in-home coffee brand? Hint: It's not Tim Hortons. Some brands are on top because they solve our problems, some win through sheer media weight, and others are reflections of our deepest desires. Which brands are #1 will completely surprise you.
