Conservative commentator Ann Coulter was among those who joked about Olbermann upon hearing the announcement.
Al-Jazeera buys Al Gore's Current TV. This is shocking because no one has ever heard of Al Gore's Current TV— Justin Stangel (@Justin_Stangel) January 3, 2013 
Another conservative commentator, Glenn Beck, tweeted about his network's attempt to buy Current TV, which was blocked because of conflicting ideologies.

And many, like Time columnist Glenn Greenwald, quickly defended the network against the unavoidable bigotry that filled the Twittersphere following the announcement.
