Nintendo was accused of antitrust behavior because of the strict licensing requirements. The United States Department of Justice and several states began probing Nintendo's business practices, leading to the involvement of Congress and the Federal Trade Commission (FTC). The FTC conducted an extensive investigation which included interviewing hundreds of retailers. During the FTC probe, Nintendo changed the terms of its publisher licensing agreements to eliminate the two-year rule and other restrictive terms. Nintendo and the FTC settled the case in April 1991, with Nintendo required to send vouchers giving a $5 discount off to a new game, to every person that had purchased a NES title between June 1988 and December 1990. GameSpy remarked that Nintendo's punishment was particularly weak giving the case's findings, although it has been speculated that the FTC did not want to damage the video game industry in the United States.

Presbyterianism is the largest Protestant denomination in Northern Ireland and the second largest on the island of Ireland (after the Anglican Church of Ireland),[citation needed] and was brought by Scottish plantation settlers to Ulster who had been strongly encouraged to emigrate by James VI of Scotland, later James I of England. An estimated 100,000 Scottish Presbyterians moved to the northern counties of Ireland between 1607 and the Battle of the Boyne in 1690.[citation needed] The Presbytery of Ulster was formed in 1642 separately from the established Anglican Church. Presbyterians, along with Roman Catholics in Ulster and the rest of Ireland, suffered under the discriminatory Penal Laws until they were revoked in the early 19th century. Presbyterianism is represented in Ireland by the Presbyterian Church in Ireland, the Free Presbyterian Church of Ulster, the Non-subscribing Presbyterian Church of Ireland, the Reformed Presbyterian Church of Ireland and the Evangelical Presbyterian Church.
