match. Hockey On January 1, 2009, the National Hockey League played its 2009 Winter Classic at Wrigley Field, pitting two "Original Six" teams – the host Chicago Blackhawks and the visiting Detroit Red Wings – in an outdoor ice hockey game. The rink ran across the field from first base to third base with second base being covered by roughly the center of the rink. The attendance for this game was 40,818. The Red Wings won 6–4. Concerts Since 2005, Wrigley Field has been opened on a limited basis to popular concerts, but not without some controversy. Local neighborhood groups have expressed concerns about the impact of concert crowds and noise on the surrounding residential neighborhood, particularly in 2009, when three concerts were added to the schedule, one conflicting with an annual neighborhood festival. List of concerts Traditions and mainstays Corporate sponsorship Wrigley Field shares its name with the Wrigley Company, as the park was named for its then-owner William Wrigley Jr., the company's CEO. As early as the 1920s, before the park became officially known as Wrigley Field, the scoreboard was topped by the elf-like "Doublemint Twins", posed as a pitcher and a batter. There were also ads painted on the bare right field wall early in the ballpark's history, prior to the 1923 remodeling, which put bleachers there. After that, the Doublemint elves were the only visible in-park advertising. The elves were removed permanently in 1937, when the bleachers and scoreboard were rebuilt. It would be about 44 years before in-park advertising would reappear. Ironically given the roots of its name, Wrigley Field had been a notable exception to the trend of selling corporate naming rights to sporting venues. The Tribune Company, the owners of the park from 1981 to 2009, chose not to rename the ballpark, utilizing other ways to bring in corporate sponsorship. During the mid-1980s, Anheuser-Busch placed Budweiser and Bud Light advertisements beneath the center field scoreboard. Bud Light became the sponsor of the rebuilt bleachers in 2006. In the early 2000s, following the trend of many ballparks, a green-screen chroma key board was installed behind home plate in the line of sight of the center field camera to allow electronic "rotating" advertisements visible only to TV audiences. By 2006, the board was set up to allow advertisements to be both physical and electronic (they can be seen in both live and replay shots). In
