A lesser-known Rockefeller tower, 75 Rockefeller Plaza, could be shopping for new tenants, Crain’s reported.

Time Warner has been managing the 34-story building since 1993, although none of its employees currently work there, a spokesperson told Crain’s. Time Warner subleases the space to a variety of tenants, and its lease is up in 2014. Sources said Time Warner will not be renewing its lease. The owner, investor Mohamed Al-Fayed, wants a tenant who will lease and manage the space, and has enlisted Cushman & Wakefield to find one, Crain’s said. Time Warner representatives declined to comment to Crain’s.

That leaves open the possibility that a very large, empty chunk of space in a prime Midtown location will become available. [Crain’s]
