How has Marketing been influenced by Artificial Intelligence?

From my experience, we are still at the premises of AI in marketing. Here are some areas of marketing where I believe AI is beginning to make interesting inroads. Copy writing is one area with a company like Persado as one example raising an interesting round ($38M if I remember correctly) to deliver AI-written content that is trained on actual engagement from the big data graph. The idea is to remove the guesswork, think manual copy testing, and embed actual results into your first draft. This apply to both B2B and B2C growth marketing.
