Less than five years have passed since the first detection of a gravitational-wave signal, on September 14th, 2015. Yet, the status of the field has changed drastically, with a growing number of detections made by a global network of ground-based interferometric detectors with unprecedented sensitivities and high duty cycles. A truly new window onto the Universe, symbolized by multi-messenger astronomy with gravitational waves, has been opened. The LIGO Scientific Collaboration and the Virgo Collaboration have developed a wide set of resources to communicate the excitement of this new field to the general public. This talk will review the main tools used to achieve this goal, that range from classic site visits, outreach publications or educational materials, to social medias, games or apps displaying gravitational-wave public alerts live. We will also describe the target audiences we have identified and show how the diversity of our collaborations is an asset to reach them out.
