Digital art on a screen network is content whose job is atmosphere rather than information. It appears in lobbies, hotels, restaurants and retail as an alternative to leaving a screen dark or looping a promotion nobody needs to see again.
Generative work suits the medium unusually well, because it never repeats. Content driven by an algorithm (reacting to time of day, weather or movement in the room) solves the problem that kills decorative loops: staff and regulars seeing the same ninety seconds several hundred times.
The caveat is licensing, and it is the part that gets skipped. Art displayed in a commercial space is a public performance in most jurisdictions, and a licence bought for personal or editorial use does not cover it. Stock footage licences in particular are commonly breached this way, quietly, at scale, across a fleet.
Second, decide whose screen it is. A display running art is not running anything else, and the case for that is real but should be made deliberately rather than by default because no one produced content this month.
