Although the .io domain names have been around as early as 1997, it is still less occupied than other generic and extremely popular top-level domains (TLDs). TLDs with the .io code are an attractive option amongst the tech and startup scene and this is largely due to the fact that the letters stand for input/output within the industry.
Input/output represents the fundamental concept of computers: every input results in an output. Businesses, companies and individuals alike can benefit from the creative freedom of choosing their favored TLD name; a meaningful, unique and concise name may be what it takes to position your business ahead of the competition.
Since there are no permanent inhabitants of British Indian Ocean Territory, the .io domain name’s applications are not related to its location. We already know why it has become the domain name of choice among many developers and entrepreneurs working in the tech industry. But it is popular as more than just a nod to computing.
As the world is experiencing a rapid period of digitization and most businesses require an online presence, you’ll need a slick and easily memorable site and domain name to stand out. The dot io domain can help achieve that. With some creative thinking, you can integrate your company’s name into a domain with io.
