A consortium of networks including ABC, CBS, Fox, Turner Entertainment and Disney have banded together to file a federal lawsuit against the Flying J truck stop chain.

Apparently, the chain of 178 travel plazas and fuel stops has taken to substituting outside commercials for their own spots in every location that has a trucker's lounge playing a service called Plaza TV. Basically, this is made possible by a little box called the segOne 2000 LS, which detects commercials in normal broadcasts, them replaces them with new ones. In this case, trucker-specific ads for Flying J, which itself turns around and charges other companies $31,250 per month for a 30-second spot on Plaza TV.

The suit alleges copyright infringement and "unfair competition."
