During the last decades, with the development of a multitude of communication platforms, social media and other offerings of information technology, communication has acquired an important role in our life. Thus the necessity and importance of science communication keeps increasing and has unavoidably become part of the scientific process. In this paper we first discuss briefly the targets of our communication strategy, the objectives and the messages. We then present a non-exhaustive list and some examples of communication methods and platforms used by the four big LHC experiments – ALICE, ATLAS, CMS and LHCb. Emphasis is given on engagement with new audiences.
