Third parties refer to individuals or groups that are not directly involved in a particular situation or transaction but may influence or be affected by it. In politics, third parties are political parties other than the two dominant ones, such as the Democratic Party and the Republican Party in the United States. They can provide alternative viewpoints and options for voters. In business, third parties often act as intermediaries between two primary parties. For example, a third-party logistics provider manages the transportation and storage of goods for a company. This allows businesses to focus on their core operations while relying on specialized services from third parties.
