The National Association of Broadcasters—which represents parent companies of NBC, CBS, and Fox, among others—yesterday moved to halt the Federal Communications Commission’s recent ruling requiring TV stations to post political ad buy data online (data the stations currently keep in paper form in their own filing cabinets—some of which CJR recently explored).

The NAB petitioned the United States Court of Appeals for the District of Columbia Circuit on Monday for

relief from the [FCC’s] action on the grounds that it is arbitrary, capricious, in excess of the Commission’s statutory authority, inconsistent with the First Amendment, and otherwise not in accordance with law.

CJR has been writing about this issue for months (with frequent help from Steven Waldman, a former adviser to the FCC). Stay tuned here in the coming days for more on this latest development and what it might mean.
