OpenAI defends advertising in ChatGPT for humanity's benefit

At Advertising Week New York, OpenAI's VP of monetization partnerships, Samantha Jacobson, defended the company's move to introduce ads in ChatGPT, framing it as a way to make AGI benefits accessible to all, since not everyone can pay for subscriptions. She emphasized consumer trust as paramount, even at the expense of revenue, and contrasted ChatGPT's intent-based advertising with traditional demographic targeting, which she called 'creepy.' OpenAI's ad business has grown rapidly: ads launched in February, a self-serve ad manager in the US in May, and by late August reached a $1 billion annualized run rate, with tens of thousands of advertisers in over 40 countries. The company reportedly targets $2.5 billion in ad revenue this year and $100 billion by 2030. Jacobson's comments come amid broader industry skepticism about ad-funded models and privacy concerns.
