Eric Boehlert at Media Matters reported yesterday Glenn Beck’s Fox show just posted another ratings low for this year. The new mark was set last Thursday when the show attracted 1.82 million viewers.

In late January and into February, the program was averaging 3 million viewers each week.   Today, the viewership is trending around 2 million — which means that in a span of just three months, Glenn Beck has lost nearly one-third of its television audience.

How soft are Beck’s current ratings? He’s now posting the type of numbers that his show used to get when he was on vacation and somebody less famous stood in for him, like when he took a few days off in late March and his show averaged 1.9 million viewers.

Beck’s been back from his March vacation for weeks now, but his ratings are roughly the same as when he wasn’t even there.

Glenn Beck has lost 1/3 of its TV audience since January | Media Matters for America.
