A more digital ecosystem is almost impossible: Google dominates the markets for search services and online advertising, its Android operating system runs on billions of cell phones, and many users prefer to use the Chrome browser to get to the Google video platform Youtube.

No wonder that the Cartel Office chose Google as the first use case to test the new rules against the Internet giants.

The pace is impressive: the new competition law is just twelve months old, and the proceedings against Google did not begin until the end of May.

The determination of a "paramount cross-market importance" heralds a new era in competition supervision.

For the first time, the Cartel Office can take preventive action against a corporation to prevent it from abusing its market power - which in this case primarily means data power.

The competition watchdogs have put themselves in attack position.

But the more difficult stage is still ahead of them.

Google will not give up without a fight.
