Alphabet's (GOOGL) - Get Report Google apologized today for allowing ads to appear next to offensive YouTube videos after high-profile firms like Mark's & Spencer (MAKSY)  and HSBC (HSBC) - Get Report pulled ads for British markets from Google sites.

The British Government also suspended its advertising on YouTube following certain public sector ads appearing alongside videos containing homophobic and anti-semitic messages.

"I would like to apologize to our partners and advertisers who might have been affected by their ads appearing on controversial content," Google EMEA President Matt Brittin said at the annual Advertising Week Europe event in London.

Britain is the second largest market for Google following the U.S., generating $7.8 billion primarily from advertising in 2016.
