.web is one of the new proposed top-level domains. The .web has been rumored to possibly be the next .COM. The new .web domain space will be the first truly generic space to compete directly with the increasingly overcrowded .COM space. It will introduce a vast new range of domain choices to businesses and individuals around the world and will be the platform for a number of innovative domain-based services.
There is shortage of quality domain names left under the current gTLDS such as .com, .biz, .org, .net. The introduction of .web will give businesses and individuals the opportunity to register more suitable, desirable and descriptive domain names.
