Al Jazeera America draws such a teensy audience — 15,000 on average during prime time, according to Nielsen — that if you dropped all of the fledgling cable news channel’s viewers into a modern NBA arena you’d leave a couple of thousand vacant seats. To place Al Jazeera America’s audience in perspective, it’s less than half of that once attracted by Al Gore’s Current TV, the channel it replaced last August. Ratings leader Fox News Channel pulls in an evening average of about 1.6 million.
