However, it is not the first time that U2 have dabbled in（涉猎） live streaming - they allowed fans to watch a Boston date of their Popmart tour in 1997 via Microsoft's MSN website.

YouTube has also experimented with live broadcasts in the past, most notably with its YouTube Live show, which premiered on 22 November, 2008 with performances from will.i.am and Katy Perry.

The company, which is owned by Google, is keen to expand its business beyond hosting short amateur（业余的） clips.

Earlier this year, it began streaming Hollywood movies like Cliffhanger to users in America. UK broadcaster Channel 4 has also announced it will offer a full catch-up service via YouTube by the start of 2010.

However, live streaming poses bigger technical issues than offering pre-recorded content, and issues over music rights may prevent the U2 experiment becoming more commonplace at any great pace.
