Al-Jazeera, the Pan-Arab news channel that struggled to win space on American cable television, has acquired Current TV, boosting its reach nearly ninefold to about 40 million homes. With a focus on U.S. news, it plans to rebrand the left-leaning news network that cofounder Al Gore couldn't make relevant.

The former vice president confirmed the sale Wednesday, saying in a statement that Al-Jazeera shares Current TV's mission "to give voice to those who are not typically heard; to speak truth to power; to provide independent and diverse points of view; and to tell the stories that no one else is telling."
The acquisition lifts Al-Jazeera's reach beyond a few large U.S. metropolitan areas including New York and Washington, where about 4.7 million homes can now watch Al-Jazeera English.
