More than 100 million registrations worldwide speak for themselves – clearly, the .com domain is the most commonly used domain extension worldwide. In its early stages, .com was supposed to be used for commercial purposes, since it is an abbreviation for the word "commerce". Today, however, it is used for all purposes – personal, professional and commercial. One of the prime reasons for registering another .com domain is if you are expanding your business. If, for example, your company is already successful in the US, and you're looking to expand it to Mexico, you could register a second .com.mx domain to cater exclusively for the Mexican .com.mx market. Additionally, many domain traders and businesses extend their domain portfolio in order to protect their brand on the internet. They then turn not only to the classic domain endings like .com, .org, .net or .info, but they also use new domain extensions like .online, .shop or .tech.
