Deal is the biggest acquisition for Murdoch since family resolved dispute over future control of media holdings

James Murdoch, second son of publishing giant Rupert Murdoch, has agreed to acquire some of Vox Media’s assets, including New York magazine, in a deal believed to be worth around $300m.

The 53-year-old publishing scion is acquiring the assets through his company, Lupa Systems, which has built up holdings in Art Basel, the traveling art fair business, and Tribeca Enterprises, the media and entertainment company co-founded by Robert De Niro, and the Indian streaming service Bodhi Tree Systems.
