Politico reports Al Jazeera is shutting down its North American operations - newsroom, editorial office, and cable channel. One presumes they will continue to cover events happening here of interest to their predominantly Arab viewership, presumably using what we'd call "foreign correspondents" or stringers.
Reading between the lines, it would appear AJA couldn't generate the needed viewership in North America and, lacking viewers, couldn't sell advertising to support their operations. To understand most business decisions, including this one, follow the money.
