Today's social networks, news websites, and viral videos compete for our attention, inundating us with information. Sometimes they urge us to take action against the plight of others: the Syrian refugee crisis, the mass violence in Myanmar. It can leave us feeling overwhelmed, perhaps as though our small efforts won’t make a difference. Or perhaps we wonder why we should care about an issue so far away. For Americans during the early 20th century, the Armenian Genocide, which began today in 1915, resonated deeply, prompting the largest mass media campaign of its time to save thousands. With the luxury of instant connectivity today, their efforts can remind us just how far-reaching we can be when humanity depends on it.
