For context, this type of advertising falls into "digital out of home" or DOOH. DOOH is going to be the next big thing (connected TV like roku/etc is the current big thing). Consider how antiquated a normal billboard is, when you could make it digital and get many more features. This vendor has a cool map you can see of all their screens. Most of them are the small screens on gas stations/stores/etc, but some are billboards. They recently signed a deal to put digital signage on top of ubers and taxis (but not inside the car). I'm not affiliated but attended a pitch of theirs. https://www.adomni.com/inventory https://www.adomni.com/inventory
