The document discusses how programmatic advertising within mobile apps has evolved over the past decade and what may define it in the next decade. It notes that in the past decade, app marketing focused on installations, gaming, social media, geo-targeting, and some upper funnel video ads, while programmatic advertising has now replaced older ad network models.
