It is shaping up to be a busy week at the European Commission which is targeting another US company - this time chip-maker Qualcomm.
It has fined Qualcomm €242m (£217m) for "abusing its market dominance" in 3G baseband chipsets by charging prices below cost to force competitor, Icera, out of the market.
Competition Commissioner Margrethe Vestager said: "Baseband chipsets are key components so mobile devices can connect to the Internet.
"Qualcomm's strategic behaviour prevented competition and innovation in this market, and limited the choice available to consumers in a sector with a huge demand and potential for innovative technologies."
It said Qualcomm sold the chipsets to Chinese giants Huawei and ZTE "with the intention of eliminating Icera, its main rival at the time".
Qualcomm is yet to respond.
The European Commission says it has approved Vodafone's proposed $22bn takeover of Liberty Global cable business in the Czech Republic, Germany, Hungary and Romania after the UK company offered a number of concessions.
Competition Commissioner Margrethe Vestager, who yesterday announced an investigation into Amazon, said: "In our modern society access to affordable and good quality broadband and TV services is almost as asked for as running water.
"We have today approved Vodafone's purchase of Liberty Global's business in Czechia, Germany, Hungary and Romania subject to remedies designed to ensure that customers will continue enjoying fair prices, high-quality services and innovative products.”
