Someone has also suggested taxing them. Maybe in some cases, they can be taxed instead of banned, although in some cases probably should just be banned.
Advertising signs might be permitted in some places inside of buildings (especially if they are advertising items being sold there (e.g. foods at a restaurant)), although even then it is probably best not to use too brightly lighted computer/television displays (which waste too much power and also produce too might light; in many cases, e-paper displays would be useful for commercial displays (not only advertising, but also e.g. business hours, which rarely change but sometimes do often enough (e.g. holidays) that it can help to occasionally change the display) that do not need to change very often), and they should also avoid being dishonest advertising.
