Digital signage (also known as dynamic digital signage or multimedia digital signage) is an advertising format that is based on the delivery of digital content through devices such as screens, projectors, touch panels or totems. Generally, these devices are located at the point of sale or in public places, and allow a company to create, manage, distribute, and publish its own content, combining the advantages of digital advertising and more conventional external advertising.

Outdoor Digital Signage
Outdoor digital signage ads are usually located in public places with a lot of traffic. A good example of this is Times Square, where digital advertising occupies the facades of buildings. Other popular locations are bus stations, gas stations, city access points or even the subway.
Launching a digital signage outdoor campaign usually requires quite a large investment, but in return you get great visibility and awareness.

Indoor Digital Signage
Digital indoor signage has more options. Here closer contact with the consumer is prioritized through smaller screens with interactive options.
The investment required for such a campaign is less than with external digital advertising, so it is within reach of companies with more modest budgets. According to some experts, this option is more likely to influence the purchase, since the consumer is at the point of sale and therefore in a situation conducive to conversion.
