This is great news for domain investors who have been buying domain hacks (like so many park.io users). The web search company (with $66 billion dollars in revenue in 2014), launches a new and important part of their business, and they put it on a domain hack.
And this isn’t the first time they have used domain hacks - they have long been a supporter. Here are a few other examples:
On December 15, 2009 Google launched its own URL shortener under the domain goo.gl using the country code top-level domain (ccTLD) of Greenland. YouTube subsequently launched youtu.be using the ccTLD of Belgium. Google owns coupons.io and spider.io, etc..
Domain hacks are awesome because they are cool, short and memorable. Google knows this because they most likely could have bought alphabet.com (which doesn’t resolve), but instead went with the domain hack abc.xyz.
