Americans across at least 75 different cities took to the streets to protest the death of Black men and women at the hands of police.

Coupled with the ongoing coronavirus pandemic, which has disproportionately affected Black communities, the killings of Breonna Taylor on May 13 and George Floyd on May 25 have sparked six consecutive days of protests. What started as peaceful demonstrations descended into violent altercations, fires and looting over the weekend as police officers deployed tear gas and rubber bullets. Twenty-six governors called in the National Guard and at least 45 million Americans were under curfew Sunday evening.

Amid the chaos, companies and their executives have been pressured to stand up and speak out against systemic racism and police brutality, and show allyship for their Black colleagues. Salesforce, Twitter and Apple were among the first to issue public statements. Overall, chief executives struck an empathetic tone, many acknowledged the power and reach of their platforms and some committed to donating money to nonprofits focused on racial injustice in addition to providing rhetorical support.

The Plug, a site that curates and analyzes Black tech trends, has kept a comprehensive timeline of executives and their statements, along with the companies’ diversity reports.
