While it seems like a simple change, the move has set the phone-maker back a hefty $3.6 million, according to the China Daily. It's the most expensive domain purchase of the year, Quartz notes, with the next highest -- whisky.com -- costing $3.1 million.
Part of the reasoning behind the change is simple -- non-native Chinese speakers tend to have trouble pronouncing the "xiao" part of the name, often getting their tongues twisted. Most will wrongly pronounce it as "shaow", but the actual pronunciation is closer to "she-ow."
Keeping it to a simple "mi" makes it easy for everyone, especially when the "mi" branding is readily seen among products such as the Redmi, MIUI and its new range of wireless routers, the Mi Wi-Fi.
The most expensive domain name of all time is VacationRentals.com, which reportedly went for $35 million in 2007. Sex.com is only third on the list, , having failed to top Insure.com's $16 million price tag.
