 No same-day substitution of a major cast member for a Live in HD performance was necessary until January 2010, perhaps because of the appeal of performing for a worldwide audience and the opportunity to appear on the subsequent DVD of the broadcast.Movie and radio broadcast revenue increased for the Met from about $5 million in 2006, Live in HD's first year, to $22 million in 2008, with Live in HD contributing the bulk of the growth.For the 2009/10 season, the Met spent about $12 million in production and received about half of the $47 million box-office gross.
