Halloween has not always been a big thing in the Philippines. But of course, with the heavy American influence, the holiday just got bigger and bigger. I think when I was a kid, trick or treating was not widespread. Only in specific communities was it done. These days, I think the same thing applies, with many barangays not having kids going around trick or treating. Very much unlike the Christmas carolers that are like flies in December. Anyhow, it looks like Halloween is just another holiday which brings out the entrepreneur in people. Sure, it is all about fun, but believe it or not, there is a business behind it as well. Here's an interesting infographic about it.
