Question: Has the maple leaf been used on any other coat of arms or country flags besides in Canada? Passage:The maple leaf has been used as a Canadian emblem since the 18th century. It was first used as a national symbol in 1868 when it appeared on the coat of arms of both Ontario and Quebec. In 1867, Alexander Muir composed the patriotic song "The Maple Leaf Forever", which became an unofficial anthem in English-speaking Canada. The maple leaf was later added to the Canadian coat of arms in 1921. From 1876 until 1901, the leaf appeared on all Canadian coins and remained on the penny after 1901. The use of the maple leaf by the Royal Canadian Regiment as a regimental symbol extended back to 1860. During the First World War and Second World War, badges of the Canadian Forces were often based on a maple leaf design. The maple leaf would eventually adorn the tombstones of Canadian military graves.

Question: What other advertisements did Microsoft release the year it launched The Life? Passage:The Life, also known as We Are ODST is a television and cinema advertisement launched in 2009 by Microsoft to promote the first person shooter  in the United States. The 150-second piece follows a young soldier through enlistment, training, and battle as an Orbital Drop Shock Trooper (ODST), analogous to a paratrooper that drops from space to a battlefield. The Life was created by advertising agency T.A.G., an offshoot of McCann Erickson. Production of the commercial itself was handled by production company Morton/Jankel/Zander (MJZ). It was directed by Rupert Sanders, and post-production was conducted by Asylum. It was filmed in Hungary, just outside Budapest in a coal mine and abandoned factories to give the sequence an "Eastern Bloc" aesthetic. The commercial and its associated campaign proved hugely successful; on the week of its launch, Halo 3: ODST became the top-selling game for the Xbox 360 worldwide, and over 2.5 million copies were sold within the first few weeks of release. The Life went on to win a number of honours from the advertising and entertainment industries, including two Clio Awards, a London International Advertising Award and several honours from the Cannes Lions International Advertising Festival, the most prestigious awards ceremony in the advertising industry.
