Amazon.com is finally starting to use half of the .co domain names they bought back in 2011.
It was back in May 2011 that Amazon announced it had acquired four .Co domains, A.co, K.co Z.co and Cloud.co for an undisclosed amount.
However the domain name did not go immediately into service.
In October 2011 Amazon announced it has acquired z.cn as a shortener for its Chinese official website at Amazon.cn which has been active since acquisition.
We have been randomly checking Amazon’s .Co single letter domains and finally found 2 of the 4 resolving.
The other domain acquired by Amazon which are still not in use are Z.co which Amazon was though to have acquired for its Zappos.com brand and K.Co which Amazon was thought to acquire for their Kindle product.
