Sony has delayed hosting a showcase event for its next games console.
In a statement it did not directly mention the civil unrest in the US, but alluded to it saying “we do not feel that right now is a time for celebration”, adding it wanted “more important voices to be heard”.
The firm had been set to unveil some of the games in development for its forthcoming PlayStation 5 on Thursday.
Google had earlier delayed an online event for the next version of Android.
The US tech giant had planned to show off new features of the mobile operating system on Wednesday, as well as release a version for testers.
On the Android Developer website, it had issued a similar statement saying: “Now is not the time to celebrate.”
It too avoided directly mentioning the protests that have followed the killing of George Floyd, a 46-year-old black man who died in police custody a week ago when a white police officer knelt on his neck.
Neither company has yet given a date for when their events will be rescheduled.
