Initially second to the 747 as Boeing's most profitable jetliner, the 777 became the company's most lucrative model in the 2000s. Program sales accounted for an estimated US$400 million of Boeing's pretax earnings in 2000, US$50 million more than the 747. By 2004, the airliner accounted for the bulk of wide-body revenues for Boeing Commercial Airplanes. In 2007, orders for second-generation 777 models approached 350 aircraft, and in November of that year, Boeing announced that all production slots were sold out to 2012. The program backlog of 356 orders was valued at US$95 billion at list prices in 2008.
