'Wow': Facebook launches 'Reactions' worldwide

By Yasmeen Abutaleb and Arathy S Nair WASHINGTON/BENGALURU (Reuters) - Facebook users around the globe can now do more than "like" a post. The social network rolled out "Reactions" - an extension of the "Like" button - worldwide on Wednesday, to allow users to express sadness, wow, anger, love and laughter. Facebook launched a pilot of "Reactions" - which allowed users to select from seven emotions including "Angry", "Sad", "Wow" and "Like" - in Ireland and Spain in October.
