Sony Corp. of America and Yahoo Inc., two of the world's most recognizable names, announced on Tuesday a broad marketing alliance in online business.

The alliance calls for the companies to create a joint Web site and a portal focused on Sony products, promoting Sony's artistic content across Yahoo's network of sites, the companies said.

"Yahoo's unrivaled expertise in Internet communications, customer relationship management, platform scalability and personalization will be instrumental in helping Sony quickly develop a world-class site and seamless customer experience," said Nobuyuki Idei, chairman of Sony Corp., the parent firm of Sony Corp. of America.

Terry Semel, chairman of Yahoo, said, "This agreement represents a significant commitment of two industry leaders to collaborate on multiple levels and extend consumer value."
