Starbucks, AT&T and Lyft are just a few of the brands that have taken to Twitter to celebrate Martin Luther King Jr. Day. With video clips, images and some of his most memorable quotes, brands are honoring King on Twitter using the hashtag ‘#MLKDay.’ Starbucks quoted him in a Tweet: “Hatred darkens life; love illuminates it.” Lyft showed a GIF of King, Jr. Delta (saluting him as a “hometown hero”), Ben & Jerry’s, Skype, Pandora, youTube, Unilever, and Google were among others.
