You didn't show us the map you were looking at, so I've attached one (below) from Wikimedia Commons. The map shows darker colors where television usage is the heaviest. So yes, as the other answer pointed out, the highest rate of television ownership/usage is in North America, particularly in the United States.
Historical fun facts:
- The first demonstration of television technology occurred in 1927.
- In 1950, the percentage of American households with a television was 9%. By the year 2000, 98% of American households had televisions -- most having multiple TVs.
