TV market would be Chicagoland area, just like the Jets/Giants tv market is the NY metropolitan area. From a which state do these teams play in standpoint, it would be Indiana just like the Jets/Giants play in New Jersey. As a point of argument, please give the full names of the teams you are referencing. As I said, a Chicago Bears team playing in the state of Indiana could still be called the Chicago Bears, but would not be referred to as an Illinois based team. Likewise, the New York Giants and New York Jets are not New York State teams.
