Companies especially ones with multinational operations and/or newly acquired businesses, typically have multiple cultures rather than a single culture.

When a business is multinational, they operate in different countries and in each country they operate in they are dealing with different cultures. Because of this, they have different cultures within their organization and operate according to where they are doing business. Successful companies will adapt to each culture so that the business runs like any other business would in their country.
