PARIS (Reuters) - French media group Vivendi (>> Vivendi) said on Wednesday it now held 23.15 percent of Telecom Italia's (>> Telecom Italia SpA) shares after buying more of the Italian company's stock on the market.

Vivendi said it purchased the shares in order to bring its stakeholding back up to previous levels following an earlier dilution of its holding after a Telecom Italia bond issue.

The move comes as French billionaire businessman Vincent Bollore, who is chairman of Vivendi, aims to turn Vivendi into a European media powerhouse.

Since Bollore became chairman in 2014, Vivendi has bought its key stake in Telecom Italia and moved back into the video games business by acquiring French company Gameloft and buying a stake in sister company Ubisoft (>> Ubisoft Entertainment), despite opposition from the founding Guillemot family.
