It's true. After 17 years as an independent company, Weather Underground has been sold, and will now be part of The Weather Channel Companies (TWCC.) As one of the founders of Weather Underground, I am excited about embarking upon this new chapter in our company's history. Having the infrastructure, resources, and content of The Weather Channel Companies will enable wunderground to create some great new products, and improve the quality and reliability of our existing content. We will now be called Weather Underground, LLC, and will maintain the wunderground.com web site as it is.
