Some 400 department stores are opening their doors today with a new name, Macy's.
Last year, Federated Department Stores purchased the May Company, including the historic Marshall Field's store on Chicago's State Street to make it the largest department store retailer.
The switch to the Macy's nameplate gives Federated more than 800 Macy's stores in 45 states, the District of Columbia, Guam and Puerto Rico. Federated has spent months switching credit cards, store signs and advertising.
Saturday morning, the retailer handed out $10 gift cards to the first shoppers at the State Street store.
The giveaway attracted dozens of shoppers who lined up outside the landmark building before it opened for its first full day as a Macy's. But not everyone is happy about the switch.
Many Chicago area consumers are upset about the loss of the historic name. And about 100 turned out Saturday to protest the change.
