两家公司控制着美国75%的市场

A court in the United States has begun hearing the US Government case against the credit card companies Visa and Mastercard for alleged antitrust violations that limit competition.

Last Wednesday, a US judge ruled in a landmark anti-trust case that the software giant Microsoft should be broken in two to prevent it abusing its market power.

Still flushed from their victory in that case, US competition regulators are flexing their muscles for a battle with the credit card industry.

The credit card giants Visa and Mastercard together control over 75% of the US market.

美国法庭已开始审理美国政府状告信用卡公司维萨和万事达违反反垄断条例，限制竞争一案。

上周三，美国一法官判决了一宗重大反垄断案，宣判软件业巨头微软公司应一分为二以限制它在市场上的垄断行为。

尚陶醉在上一案件的胜利中的美国反垄断官员们又开始摩拳擦掌准备下一场与信用卡公司的较量。

信用卡业巨无霸维萨和万事达控制着美国75%的市场。
