Consumers Union and Common Cause have teamed up on a petition to deny the merger of Comcast and Time Warner Cable.
They call it an "unprecedented, monumental step in the direction of further consolidation of Big Media."
Both are veteran critics of media mergers, so the opposition is not a big surprise.
