$1mn paid to add just one letter to domain name

London: It may be the most ever paid for a single letter of an Internet address.

A British travel company has paid £560,000 ($1.1 mln) for the domain name cruises.co.uk, a price that is effectively $1 million just for the letter 'S' since it already owns the address cruise.co.uk.

The sum shatters the previous record for a .co.uk domain of $300,000, paid in October last year. Seamus Conlon, whose company bought the address from a German travel company, said it was a necessary move to retain dominance in the rapidly growing market for ocean cruising.

"'Cruises' is consistently ranked first on Google, with 'cruise' just behind," he said.

"We wanted the top positions so that when Internet users are searching for deals... we are the first port of call." While the purchase is a record for Britain, it is a long way behind the huge sums paid for more the popular .com addresses.

The current most-expensive domain is sex.com, which was bought for $12 million in 2005. Running close behind is porn.com, snapped up for $9.5 million last year.
