Question: In January 2010, YouTube launched an experimental version of the site that used the built-in multimedia capabilities of web browsers supporting the HTML5 standard.

Question: 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.
