Startup advertising firm Adzookie has latched on to a high-profile way to publicize itself: by turning homes into massive billboards. In exchange, Adzookie says it will pay the house owner’s mortgage every month for as long as the home stays painted. Adzookie launched the offer on its website Tuesday — and by late afternoon, the company had already received more than 1,000 applications, according to Adzookie CEO Romeo Mendoza. One even came from a church.
