Through a post on its official blog, Google revealed that Google Photos has reached the major milestone of drawing 100 million monthly active users, among other interesting details regarding the unlimited picture service.

Google Photos, which was spun off from the Google+ social network back in May, comes with apps that are available on the web and on iOS and Android devices. The service was praised for both the simplicity it offers and its combination of the best features offered by rivals such as the Carousel of Dropbox, the iCloud of Apple and Flickr of Yahoo.

Hitting the 100 million monthly active user mark is an amazing achievement for Google Photos. In comparison, Twitter and Pinterest both took around five years before growing their user base to that size. Even the popular Instagram took about two and a half years to hit that figure.

The growth of users for Google Photos could have been aided by the fact that Google allows anyone with a Gmail account to sign up for the service.In addition, the migration of users from the old photos service of Google+ to Google Photos could have given it a head start. However, these do not take away from what Google Photos was able to accomplish over a relatively short period of time.

In Google's blog post, the company also revealed other interesting facts about Google Photos, such as that the service has been able to free up the equivalent of 3,720 TB in storage. According to Google, that is like filling up the memory capacity of a 16 GB device with pictures daily for 637 years.

Other interesting facts include food being what Google Photos users take a picture of the most followed by cars, weddings being the most photographed event, users taking pictures of dogs more than any other animal, and Paris being the top pictured place.

Additionally, Google revealed that the top subject searched for in Google Photos is "babies" and users have created over 15 million collages and animations. The sky, mountains and beaches also fall among the top 10 things Google Photos users take pictures of, and searches for "me" fall under the more popular search terms.
