Following the successful introduction of the .xxx extension in 2011, a sequel was to be expected. ICM Registry, which also manages .xxx, has expanded its catalogue of extensions with .adult, .porn, and .sex - three extensions with a very specific, but also very large target audience.
The adult entertainment industry is one where, economic crisis or not, a lot of money is spent, and anyone active in the industry can now select domain names from three extensions that align with their products and services.
With the addition of different extensions, many interesting domain names are still available. Unlike with .xxx domains, it is not necessary to prove that you are active in the "sponsored community".
