Since the breakthrough the CNNs achieved in different domains of computer vision and even natural language processing, most companies have integrated this deep learning solution into their computer vision echo system. For example, Google uses this architecture for its image search engine, and Facebook uses it for doing automatic tagging and more:

CNNs achieved this breakthrough because of their architecture, which intuitively uses the convolution operation to extract features from the images. Later on, you will see that it's very similar to the way the human brain works.
