IHOP Corp. announced a change of its corporate name to DineEquity Inc. to reflect its ownership of multiple restaurant brands. The change was necessitated following the acquisition of the Applebee’s chain, said Julia A. Stewart, chairman and chief executive officer of Glendale-based IHOP Corp. “With Applebee’s and IHOP, we have brought together two great brands, and we are beginning to demonstrate how we are more successful together, than we could ever have been apart,” Stewart said. “Our name change to DineEquity reflects the promise of our newly combined company.”
