Weather Underground Reaches Milestone -- One Million Photos Submitted by Its Website Fans

WunderPhotos Demonstrates the Success of Web Businesses Seeking User-Contributed Data

SAN FRANCISCO, CA--(Marketwire - July 28, 2009) - Weather Underground, the world's first online weather service, today received its one-millionth photo submission for its popular photo section WunderPhotos.

Launched in 2002, WunderPhotos has become one of the most popular sections on wunderground.com, attracting weather enthusiasts and photography lovers alike. The section features user-uploaded photographs depicting current weather conditions, wildlife and almost any outdoors subject matter. WunderPhotos often features images of significant current weather events such as hurricanes, floods, snow storms, and even solar eclipses -- all submitted by fans of the site.

Weather Underground President Alan Steremberg says of this milestone, "The one-millionth WunderPhoto is a true testament to the power of enabling your users to drive content on your website. With the help of our users, what started as a pure weather site has turned into an interactive weather community."

User-generated content is at the backbone of Weather Underground's technology. The most valuable user-contributed data on wunderground.com is generated by Weather Underground's network of over 16,000 backyard meteorologists whose personal weather stations provide the company with more weather data points than any other weather service. This online community is also maintained through the contribution of live weather webcams and the open dialogue generated by the popular blogging section.

"The one-millionth WunderPhoto -- a stunning wildlife shot submitted from a fan in Canada -- demonstrates the wide array of subject matter that users upload to WunderPhotos. Constantly on the cutting edge of technology, Weather Underground continues to push Internet boundaries by incorporating user-based content into its many online applications," said Steremberg.
