YouTube tweaks advertising algorithm
Found on BBC News on Monday, 30 October 2017
The update comes after YouTube made changes to the way videos were monetised, to stop ads appearing alongside extremist content.
In April and May this year, YouTube acted after investigations revealed that ads for big brands were being regularly shown on racist videos or those that encouraged violence against particular groups.
So it looks like what today gets called "extremist content" made enough money for them so they need to shuffle ads around for compensation.
