Mattel Interactive is rapidly losing value as the company fails to find a buyer. When Mattel put its interactive division on the market five months ago analyst felt that it might fetch bids as high as $1 billion, less than a third of what Mattel had put out when it purchased The Learning Company. Mattel's treatment of the division as a discontinued operation, along with the sale of Mattel Interactive's interest in Cyber Patrol, has brought estimates down to $300 million.
