Party City makes and sells the goods for a well-dressed party. The #1 retailer of party supplies in the US, Party City operates more than 900 company-owned and franchised locations -- most under the Party City banner -- and some 300 seasonal Halloween City stores mostly across North America. The shops sell balloons, decorations, tableware, costumes, and more for birthdays, anniversaries, weddings, and other special occasions. Party City's stores and e-commerce site (PartyCity.com) are supplied by its manufacturing and wholesale arm Amscan, which also supplies other party chains, discount and grocery stores, and gift shops around the world. Founded in 1947, the company went public in April 2015 and is majority owned by investment firm Thomas H. Lee Partners.
