The earliest racial justice hashtag we examine in #HashtagActivism. On January 1, 2009 Oscar Grant is shot dead by BART Police in Oakland, California. YouTube is the primary platform for sharing cellphone video of the incident, as Twitter – still a new platform – does not yet allow video embedding. Despite this limitation activists begin to use the hashtag #OscarGrant to mobilize street protests on Twitter and share updates and information about the case. Read about how this early use evolves from Oscar Grant’s killing to that of Trayvon Martin in Chapter 4 of #HashtagActivism.
