Monopoly is the colloquial term, but this is actually anti-trust. A trust does not require domination of a single market. Antitrust laws focus on companies who use their position to limit competition. My opinion: * Monopolies tend to focus dominating a single market to raise rates. Google essentially has a monopoly on the search advertising business. * Trusts tend to utilize there wide-spread reach to drive down rates in non-core markets in order to server their primary market. Amazon demonstrates trust-like patterns through their bundling of unrelated services with Prime.
