Just Curious

In most sports, the emphasis is on the championship round of the playoffs or the tournament. We have the Super Bowl. The World Series. The Wimbledon/U.S. Open/French Open Championships, the NBA Finals, the Stanley Cup and so on. Why is it that College Basketball emphasizes the semifinal round--the Final Four--instead of the NCAA Championship game? All the pre-tournament hype is about "The Road to the Final Four". I'm not complaining. It just always struck me odd. Can someone out there explain what the deal is?
