Joint venture
A business owned jointly by two or more companies.
A joint venture is an enterprise two or more companies own together, often 50-50, to enter a market or share a capability neither wants to build alone.
Joint ventures complicate ownership because neither parent controls the venture outright, so neither can honestly claim the brands. Häagen-Dazs outside North America is operated by the Froneri joint venture, while General Mills owns the brand in the United States and Canada, which makes "who owns Häagen-Dazs" a question with two correct answers.
