Madison Avenue, New York, is famous for hosting several advertising agencies. Martin Sorrell, CEO of S4 Capital, previously led WPP plc and is a Madison Avenue veteran.

A penthouse condominium in the former Sony building is set to hit the market for a record $150 million, the New York Daily News says. The listing at 550 Madison Ave. will be the most expensive residential listing in Manhattan real estate, beating out the previous priciest abode: the penthouse at One57 in Manhattan's midtown.

That residence was bought for $100.47 million last month, the newspaper said.
