In less than five months, Google Photos has already hit a major milestone with more than 100 million monthly active users. To put the rapid adoption of Google Photos in perspective, it took Pinterest and Twitter almost five years to hit the 100 million mark. Even Instagram, with its explosive popularity when it launched in 2010, took around two and a half years to reach the same uptake among users.
Google’s unlimited photo service, which was spun off from the company’s Google+ social network in May, comes with apps available on Android, iOS and on the web. Google Photos was hailed at launch for its simplicity and for combining many of the disparate features of competitors like Dropbox's Carousel, Apple's iCloud, and Yahoo's Flickr into a single service.
The online photo storage has been a notoriously tough tech problem to crack, as users entrenched in one service find it difficult to switch to another. When a good one comes along, it tends to keep users hooked, as Google's apparently has. Granted, Google makes it easier to sign up as it gives the service away on the web to anyone with a Gmail account. It also may have had a head start by migrating users of its old Google+ photos service over to the new one.
Google also released some interesting factoids on how people have used Photos thus far. For instance, Google has freed up 3,720 terabytes of storage on users' smartphones thanks to its auto-upload feature. And it may not come as a surprise, but mountains, beaches, and skies all crack the top 10 list of most-photographed scenery. Google Photos algorithmically organizes your library so searching for any one of those identifiers should pull your picturesque landscape shots.
