The funds will go to help the victims and their families. The British Red Cross reported it received more than £10 million ($13 million) in donations in the 12 hours following the concert. Despite time zone differences, networks from at least 50 countries broadcast the concert live, which was simultaneously streamed live on various platforms, including Twitter, Facebook and YouTube.
