Word on the street is that Google will comply with Europe's demands to change the way it runs its shopping search service, a rare instance of the internet giant bowing to regulatory pressure to avoid more fines. 

Google had a deadline which expired yesterday to tell the European Union how it planned to follow an order to stop discriminating against rival shopping search services in the region.

A Google spokeswoman said it is sharing that plan with regulators before the deadline expires, but declined to comment further.

The EU fined Google a record 2.4 billion euro in late June for breaking antitrust rules by skewing its general search results to unfairly favor its own shopping service over rival sites.

The company had 60 days to propose how it would "stop its illegal content" and 90 days to make changes to how the company displays shopping results when users search for a product.

Those changes need to be put in place by September 28 to stave off a risk that the EU could fine the company five percent of daily revenue for each day it fails to comply.

"The obligation to comply is fully Google's responsibility", the European Commission said in an emailed statement, without elaborating on what the company must do to comply.
