The rejection of Sky TV's and Vodafone's merger is bad news for the pay TV firm's investors, who sent its share price diving by 17 per cent when the market opened this morning.
The scuppering of the deal is also bad news for anyone hoping that Sky's grip on live sport events will loosen - at least in the short term.
Sky's dominance of the live sports TV market was central to the Commerce Commission's refusal of the Vodafone deal, which would have reduced costs for both businesses and allowed them to sell internet and mobile packages with pay TV.
"Given the merged entity's ability to leverage its premium live sports content, we cannot rule out the real chance that demand for its offers would attract a large number of non-Vodafone customers," commission chair Mark Berry said today.
Live sports has long been the keystone to Sky TV's service.
