Hastings wrote in the internal memo to staff, "We had hoped this was an awful anomaly never to be repeated.
"Three months later he spoke to a meeting of our Black Employees @Netflix group and did not bring it up, which was understood by many in the meeting to mean he didn't care and didn't accept accountability for his words."
In a statement on Twitter, Friedland confirmed his departure, saying that he felt "awful" for what he had done. "Leaders have to be beyond reproach in the example we set," he said, "and unfortunately I fell short of that standard when I was insensitive in speaking to my team about words that offend in comedy.
"I feel awful about the distress this lapse caused to people at a company I love and where I want everyone to feel included and appreciated. I feel honoured to have built a brilliant and diverse global team and to have been part of this collective adventure in building the world's leading entertainment service."
He also later tweeted out a follow-up, seemingly still not quite understanding the full gravity of his actions. In the since-deleted tweet, Friedland wrote, "Thanks. Rise high, fall fast. All on a couple of words …"
As chief of communications at Netflix, Friedland was responsible for media and content publicity for the service's original series, films and specials in 190 countries around the world.
His replacement is yet to be named.
The scandal follows the continued success of the streaming service, which recorded 125 million subscribers worldwide at the end of the first quarter and expects to add 6.2 million in the second quarter.
