WGN (720 AM) is a radio station in Chicago, Illinois, USA. It is owned by the Tribune Company, which also owns the flagship television station WGN-TV, the Chicago Tribune newspaper and Chicago magazine locally. WGN's transmitter is located in Elk Grove Village, Illinois. The station has a news-talk format and is the flagship station of the Chicago Cubs, the Chicago Blackhawks, Northwestern University football and men's basketball, and was the longtime flagship station of Paul Harvey until his death on February 28, 2009. WGN is usually the top rated radio station in Chicago and is one of only a handful of American talk radio stations to have all of its programming originating locally.[citation needed] Since around 1990, WGN has been mainly a news and talk radio station. WGN broadcasts news, weather, traffic and sports every hour. Pat Hughes and Ron Santo serve as the play-by-play team for all games of the Chicago Cubs, and the broadcasts are known as the Pat and Ron Show. WGN is also the radio home of Northwestern Wildcats football and basketball games. WGN is a high-powered clear channel AM station (50,000 watts), which during nighttime hours is often audible over much of the USA, parts of Canada, and sometimes as far away as Australia and South America.[citation needed] The station also has a 24/7 Internet stream on its website, which carries the station's broadcast programming except for commercial breaks and Cubs games, when public service announcements, station promotions, host-read commercials and alternate programming, is played instead. WGN is responsible for activation of the Chicagoland Emergency Alert System when hazardous weather alerts, disaster area declarations, and child abductions are issued. - wikipedia.org

A portion of Michigan Avenue, a north-south street in Chicago, starting just north of the Chicago River is referred to as the Magnificent Mile, or sometimes simply the Mag Mile. It contains a mixture of upscale department stores, restaurants, high-end retailers, office buildings and hotels, and caters primarily to tourists and the affluent. The area also has a high concentration of the city's major media firms and advertising agencies, including the Chicago Tribune newspaper. Originally Michigan Avenue ran along the shore of Lake Michigan downtown just to the east of the Illinois Central Railroad, but natural and artificial land filling processes have moved the shoreline many blocks to the east.
