Many indoor companies allow advertisers to individually pick locations. Advertisers are able to choose exact locations in a market. The advertiser can supply art, but some indoor ad companies have art departments that also can design a campaign. Large, national brands that are placed nationally generally use their own art, says Jacobson, while smaller, local businesses use their in-house art department. Some companies offer a 11 by 45 for above urinals.
Some companies sell an entire restroom.
For example, if there are a half-dozen billboard spaces in a restroom, they are all sold exclusively. A company can, however, use different art or promote different products. Ads are mounted, often in frames, and installed. Indoor advertisers produce the posters, install and maintain them. Timelines vary with number of markets and art production.
