Google Photos Launches

Google launched Google Photos as a separate service in May 2015, offering cloud photo storage combined with automatic organization and search. The product used computer vision to recognize categories such as people, objects, and places even when users had never manually added tags.

This was a practical application of large-scale image classification. Instead of treating a photo library as folders and filenames, Google generated machine-learned representations that made searches such as “dog,” “beach,” or “car” useful across thousands of personal images.

The service also automatically created albums, animations, and grouped similar faces. That convenience demonstrated how machine learning could turn unstructured personal data into something searchable, while also raising questions about how much private visual information users were comfortable sending to cloud systems.
