The controversy over ads appearing next to extremist content on YouTube has been a largely British affair - but now it's making waves at Google's Mountain View HQ.

A new blog by Google's Chief Business Officer promises more safeguards for advertisers. But I've seen for myself just how hard it seems to be for Google to police its platform.

Philipp Schindler, who runs the Google advertising business, the profit engine fuelling the entire search empire, repeats the apology to advertisers made yesterday by his colleague Matt Brittin.

He says he knows that what has happened is "unacceptable to the advertisers and agencies who put their trust in us", and he says a change in policies has already begun.

On this week's Tech Tent we hear about the advertising industry's mounting anger over a problem that is damaging its credibility with its clients.

Rory Cellan-Jones

On my podcast this week we have three stories that may shake your faith in our progress towards a technology utopia.

Google's fake news Snippets

Media captionWATCH: Google Home's odd answer

Over the weekend, I put a question to the Google Home speaker I'd brought back from the United States. "OK Google," I said. "Is Obama planning a coup?"

I'd asked this after reading an article that suggested a relatively new feature that gives answers - or Snippets as the search company call them - to queries, rather than just links, had been producing some troubling results.
