The number of domain names registered under the Top Level Domain of .Biz has fallen under 2.5 Million.
The extension owned and operated by Neustar (NSR) seems to have been effected by the new gTLD’s.
As you can see from the chart .Biz was slowing growing until early this year when the new gTLD’s started to launch and now is moving the downward direction:
.XYZ has topped 650,000 registrations.
.Berlin in the last week past the TLD’s .Tel and .Name with over 151,000 registrations (with about 75,000 being given away for free)
.Club has broken through the 125,000 domain mark passing .Pro and .XXX.
