Publishers offering "Digital Billboard" spots

A digital billboard is a screen by the road, in a station or in a shopping area that shows an ad in a short loop of messages. JCDecaux and TVS sell screens like this, and a direct takeover can fill the whole loop.

How it's sold: Owners sell it through their sales teams, and some also sell programmatically. The advertiser picks the screens, the dates and the share of the loop.
Typical price: On request, usually as a flat fee per week or per screen.
What you supply: A video or still image in the screen's size and format, often with a few seconds of motion.
Best for: Local awareness and reaching many people in one area quickly.
Before you buy: Get the play length, how often the ad repeats and which screens are included.
