Regional or cultural celebrities

Each country has its own independent celebrity system, with a hierarchy of popular film, television, and sports stars. Celebrities who are very popular in one country, such as India, might be unknown abroad, except with culturally-related groups, such as the Indian diaspora. In some cases, a country-level celebrity might command some attention outside their native country, but not to the degree that they can be considered a global celebrity. For example, singer Lara Fabian is widely-known in the French-speaking world, but only had a couple Billboard hits in the U.S., whereas singer Celine Dion is well-known in both communities.
