Which of the following best describes the G20?

"With the G20 growing in stature after its inaugural leaders' summit in 2008, its leaders announced on 25 September 2009 that the group would replace the G8 as the main economic council of wealthy nations. Since its inception, the G20's membership policies have been criticized by numerous intellectuals, and its summits have been a focus for major protests by anti-globalists, nationalists, and others. The heads of the G20 nations met semi-annually at G20 summits between 2009 and 2010. Since the November 2011 Cannes summit, all G20 summits have been held annually."
