The word 'holiday' is the most popular search term on the internet and more than 90 per cent of travel companies have it as one of their five top key words to reach customers online.
The owners of internet domain 'www.holiday.com' will be selling it after almost 16 years at World Travel Market at London Excel on November 5, and experts say it could well become the most expensive web name when auctioned for an estimated £20million, reported DailyMail.
Some experts also expect it to surpass the existing record of £21.5 million paid for www.insurance.com in 2010.
Major travelling firms have been battling to possess the domain mane, the report added.
