The Walt Disney Co. is expected to announce today (Tuesday) that it will launch a new website, www.family.com, aimed at young mothers. The company said that while ads for Disney movies will appear on the site, it also plans to sell ads to other companies. ""We want to be clear that 'Disney' does not necessarily mean Disney-branded products and services," Paul Yanover, managing director of Disney Online, told the Associated Press Monday. "It means Disney as a reliable brand. We don't just want to push Disney products."
