Share: AT&T Inc (NYSE: T) subsidiary WarnerMedia — which in turn owns HBO Max — is planning to charge $9.99 per month for an advertisement-supported version of its streaming service, CNBC reported Wednesday. What Happened: HBO Max without advertising costs $14.99 per month, which is equivalent to what the subscribers of the company’s pay-TV subscribers with premium bundles pay. AT&T CEO John Stankey said that the HBO Max’s ad-supported version will expand the service’s reach to include those who are more cost-conscious, as per CNBC. “Whether a customer chooses to buy the ad-supported product or buy the straight subscription product, it’s accretive in the same ways to our business,” said the executive.
