You might recall that News Corp. scrapped plans earlier this year to move its struggling social networking site into 420,000 square feet of space in Playa Vista. The decision was part of a cost-cutting move. Trouble is, as reported by the FT's Matthew Garrahan, News Corp. is stuck with a 12-year lease worth about $350 million. No luck yet in subleasing the digs - and by next June the rent will increase to nearly $2 million a month.
