Al Jazeera America will be closing its shutters by April 30 this year, the network announced on Wednesday. The Qatar-based news network was launched in the United States in 2012. Chief executive officer Al Anstey said, in a memo, that the company’s business model was “not sustainable” among challenges in the American media marketplace, reported The New York Times.

Reports say that low viewership and plummeting oil prices are behind the channel shutting down in the US, though a spokeswoman denied that. The channel will expand its digital presence after shutting down, it said. It was also mired in controversy from the beginning, from being involved in a lawsuit with one of its carriers, AT&T, to senior staff not being included when network employees decided to form a union.

The network also ventured into the US at a time when other channels were downsizing, The Guardian said. It bought up Al Gore’s sinking news network Current TV in an attempt to relaunch it, but is involved in a lawsuit regarding that as well.
