I can explain what happened.
I work for Weather Central in Madison, Wisconsin. In December we were purchased by the famously rich Rothschilds of Europe and they brought in a charismatic new superstar CEO. Seven months later, they cashed out to the tune of +$15 million, selling to our historical nemesis and competitor, Weather Services International.
WSI is owned by The Weather Channel Companies, which is an umbrella company for The Weather Channel (duh) as well as Weather Underground, which they recently bought. (TWCC is owned by NBC Universal, which is owned by Bain Capital and Blackstone Group. That means I now work for Mitt Romney.)
This consolidation is complete. Over 90% of the worldwide weather services business is now owned by TWCC, which used that considerable power to negotiate a contract with Google. The contract stipulates that TWCC (and their sub-companies) will provide data to Google, and in turn Google would eliminate its weather API, because TWCC has its own weather APIs (more than one of them now, in fact). The API at my company is cleverly named DataCloud: http://datacloud.wxc.com/?vs=0.9.
This consolidation is definitely good for TWCC, which will never again have to worry about competing in the marketplace. The monopoly will last until a disruptive technology displaces it in a couple decades, if it's anything like other stale monopolies. Unfortunately, it is definitely bad for the other 7.01 billion people on the planet, who now only have one source for weather data.
