Just a dot on the horizon at first, the bug-like and surprisingly quiet electrically-powered craft buzzes over Paris and its traffic snarls, treating its doubtless awestruck passenger to privileged vistas of the Eiffel Tower and the city's signature zinc-grey rooftops before landing him or her with a gentle downward hover.

European Union antitrust regulators took aim at Google's lucrative digital advertising business in an unprecedented decision, saying Wednesday that the tech giant must sell off some of its ad business to address competition concerns.

Two of the U.K.'s biggest mobile phone operators agreed Wednesday to merge their businesses to capitalize on the rollout of next-generation 5G wireless technology in the country.

When the pandemic hit three years ago, Amazon was one of the few businesses that thrived.
