The National Opera of Greece promoted the famous Aida through social networks. Communication Effect supported the online communication of the show through the twitter account www.twitter.com/Aida_GR. The online competition was divided into “four acts”, the same number as the acts of the show. In every act of the online contest, 5 lucky twitter users earned double invitations for the show. The contest lasted two days and offered a total of 40 double invitations. The idea was highly accepted by the users because of its simplicity, spontaneity and immediacy.
