Digital ad space is cheaper than traditional billboards
With digital displays, there are no printing costs for any vinyl or other poster materials. The advertisement is simply an image that is displayed on a large screen, so there is no concern about printing quality or weather damage. Not only are you saving on printing costs, you are also saving on time. If an advertisement is displayed only at certain times, you are allowing your ad to skip that times of day where there isn’t nearly as much traffic and is likely just costing you money.
