Al Jazeera America has gone live, broadcasting to 48 million homes in the US.
It has been tipped as the most ambitious news project in the US for many years.
Headquartered in New York, the channel has 12 bureaus in major cities around the country, three broadcast centres, and a team of nearly 900 journalists and staff.
Viewers will receive more than 14 hours of live news, magazine and discussion programmes daily with news updates at the top of every hour 24/7.
“We will take full advantage of our extraordinary reporting resources to give our viewers the most up-to-date information available no matter when they tune in,” President Kate O’Brian said ahead of the launch.
