well, now that IBM is buying out everything but the TV channel, here's something interesting about this, i decided to type up the potential new TWC domain names and got some results.
so far i got this:
NBCweather.com (if TWC rebrands to NBC weather if NBCUniversal keeps TWC the channel) : got nothing, CBSweather.com (if CBS buys the TV side out and renames it): it redirects to the CBS corporate site.
theweatherchannel.com and weatherchannel.com (if TWC name is retained in new ownership or NBCUniversal keeps it): redirects to weather.com.
ABCweather.com (in event of Disney buyout and name change): a domain squatter bought this domain and using it to try to harm computers.
FOXweather.com (in event of Fox buyout and name change): went to a site unaffiliated to 21st Century Fox, so it's possible they may redirect to Fox News' website's weather section if Fox does buy it out and renames it.
CNNweather.com (in event of Time Warner/Turner Networks buyout and name change): nothing, no site exist.
so basically, looks like CBS may buy out The Weather Channel TV network and maybe rebrand it to CBS Weather with the fact the CBSweather.com domain redirects to cbscorporation.com
