The hotel industry originated in the 6th century BC and is one of the oldest industries. Early inns provided only basic shelter and floor space for travelers and animals. Over time, hotels developed different classifications based on market segment, size, level of services, ownership, and star ratings. ITC Limited entered the hotel industry in 1975 and currently owns over 100 hotels across India operating under various brands like ITC Luxury Collection, Welcome Heritage, and Fortune Hotels. The key aspects of hotel operations include rooms, food and beverage, sales and marketing, security, and human resources.
