The Weather Underground purchased by The Weather Channel

The Weather Underground, started in AOSS in the 80’s, has been acquired by The Weather Channel.

“It is truly amazing what can come out of undergraduate projects at Michigan,” AOSS Professor Perry Samson states in an e-mail.

The Weather Underground began as a telnet session so Samson could get weather data before a 9 A.M. class. With NSF support, it evolved to build one of the first interactive graphics tools (Blue Skies) using gopher technology.

The students involved, including Alan Steremberg, Jeff Masters, and Chris Schwerzler plus a former staff member, Jeff Ferguson, regrouped the effort a few years after graduation into the commercial site  

The Weather Underground has grown to be one of the top 100 most visited web sites in the United States and is expected to grow even faster after the acquisition.

In a New York Times interview, chairman and chief executive of the Weather Channel Companies, David Kenny, praised Weather Underground for having a “hard-core audience.”

Mr. Kenny also stated that will continue to exist on its own. The data collected by Weather Underground will be harnessed to improve the Weather Channel’s forecasts.
