However sales dropped in the following two years, and the product was reformulated and renamed to the Chicken Whopper to align the product with the company's Whopper Sandwich. A change of ownership of Burger King in 2004 prompted another reformulation of the product into the BK Baguette product line that focused on a more health-oriented product. This new formulation proved unpopular and was replaced in 2005 with the TenderGrill chicken sandwich. The TenderGrill sandwich was introduced as part of a series of sandwiches designed to expand Burger King's menu with both more sophisticated, adult oriented fare and present a larger, meatier product that appealed to 24- to 36-year-old males. Burger King was the first major fast food chain to introduce a grilled chicken sandwich to the marketplace, beating rivals Wendy's by six months and McDonald's by four years. These two chains also went through a series of reformulations and naming schemes for their grilled chicken products.
