Basketball is the most popular sport in the Philippines. So many people follow and play it.
Most neighborhoods will have a public basketball court and chances are, there will always be people playing. Most courts are sponsored by politicians, like the one above. Every school also has basketball courts, in fact my old school had 2 full courts and several half courts.
When I was heading to the States, a couple of the airports I went through had TVs setup to entertain people who are waiting. I noticed that in the States, they played the news, in Korea, they played a Korean TV show (not sure what it was) and in the Philippines, they played basketball. The only other sport that I would consider bigger than basketball is boxing, but only when Manny Pacquiao is fighting, otherwise, it’s no contest. If you need gift ideas for people here, consider a basketball or a jersey from their favorite team
