Both the English and the Arabic channels actively covered the protests, violence and political upheaval that have become known as the Arab Spring.
Current, meanwhile, began as a groundbreaking effort to promote user-generated content. But it has settled into a more conventional format of political talk television with a liberal bent. Gore worked on-air as an analyst during its recent election night coverage.
Its leading personalities are former New York Gov. Eliot Spitzer, former Michigan Gov. Jennifer Granholm and Cenk Uygur, a former political commentator on MSNBC who hosts the show called "The Young Turks." Current signed Keith Olbermann to be its top host in 2011 but his tenure lasted less than a year before it ended in bad blood on both sides.
Current has largely been outflanked by MSNBC in its effort be a liberal alternative to the leading cable news network, Fox News Channel.
Current hired former CNN Washington bureau chief David Bohrman in 2011 to be its president. Bohrman pushed the network to innovate technologically, with election night coverage that emphasized a conversation over social media.
Current TV, founded in 2005 by former vice president Gore and Joel Hyatt, is expected to post $114 million in revenue in 2013, according to research firm SNL Kagan. The firm pegged the network's cash flow at nearly $24 million a year.
