Paris-based Zodiak has bought an 8% stake in UK independent TV producer Shed Media. Another 2% more and Zodiak could stymie Time Warner, which is trying to buy Shed. Cyrte Investments, the investment company of Endemol-founder John De Mol, sold its 7.8% Shed stake to Zodiak on June 1. But the deal has only just come to light in a Stock Market footnote to another Shed investor, Aviva, selling 6% of its shares.

Last month, Zodiak closed a deal to acquire U.K.’s RDF Media Group, already creating the third largest independent TV production company in the world.

Time Warner could pay up to £90 million ($135 million) for Shed. The studio wants Shed, which makes Supernanny for America, because it wants to expand overseas, replicating the success it has had in America with hit shows such as The Wire and Gossip Girl – both of which have exported well. It recently hired ex-Tiger Aspect managing director Andrew Zein to buy independent TV producers and grow Warner Bros’ UK production business.
