Is IHG owned by Hilton?

Excuse me, I'm curious about the ownership structure of the hospitality industry. Specifically, I've heard people mention IHG and Hilton as two prominent names. Could you clarify for me if IHG is actually owned by Hilton? I'm trying to get a better understanding of the corporate landscape in this sector, and any information you could provide would be greatly appreciated. Thank you in advance for your time and expertise.
