I think English was used in this web
sites because is a language most cultures know after their own and it results
easier for them to understand what the sites are showing. Websites uses images and videos in order to
have a better understanding of the culture they are showing. For example the
site that shows Thai’s celebration of new year, beginning the article with text
and then show images about what they’re
talking and also in the middle of the article appear some videos that reflect
not only the way Thai celebrates new year, but also some other aspects of their
culture.
From this site I learned that "Sawadee Pii May" means happy new year in Thai and they celebrate it throwing water to other people even if they are foreign. This is a representation of their belief that water away bad luck and purifies.
