I still don't rlly understand what it is
From the above website:

"Cultural diffusion is the spread of cultural beliefs and social activities from one group to another. The mixing of world cultures through different ethnicities, religions and nationalities has increased with advanced communication, transportation and technology."

Here's an example. Most people outside of Italy had never heard of pizza until the late 1940s. Italian immigrants brought pizza here spreading their culture to different lands.

Ask some older people how much the United States customs have influenced people in your area. Perhaps TV and the internet have helped this cultural diffusion.
So I am it kinda like free trade or??
Is it kinda like free trade***
Not exactly, although usually this cultural diffusion works both ways. Immigrants adopt some of the customs of their new land, while the natives adopt some of the immigrants' customs.
