I'd like to learn about Chicago please. 
 Chicago Metro area is the third-largest media market in North America, After New York City and Los Angeles. 
 Yes, I wanted to learn about their media. 
 I do not have any further information on the buildings of Chicago, but I can inform you on the site of the Chicago Portage, the Eastern and Western Universted States hub was central for people travel from the Eat to the West or visa versa. 
 Is there any other history in regards to buildings in Chicago?
