We might be in the AdTech business, but not even we like being inundated with unwanted ads. Some of us even use Ad Blockers. But, we also believe in an open and fair internet and in many cases, advertising is necessary. It powers freedom of speech, and allows access to information on any topic, at any time. Advertising isn’t a problem, the ecosystem is. KMTX is committed to improving this ecosystem for users and publishers through science and innovation.
