Two giant media companies have been hit with an eye-popping $10 billion lawsuit accusing them of race discrimination in violation of the 1866 Civil Rights Act, TheWrap.com reports. The companies are AT&T and DirecTV.

Passed in the aftermath of the Civil War, the Civil Rights Act affirmed that all citizens of the U.S. had equal protection under the law.

The suit by the National Association of African-American Owned Media alleges that the two companies, which are in the process of merging, refuse to carry channels by and advertise with media that is 100% owned by African Americans.

The suit was filed Dec. 2 in a California federal court, TheWrap reports.

NAAAOM says it represents “at least one” television production and distribution company “that is 100% African American-owned,” the story reports, although that company is not named.

The lawsuit further states that “the unnamed company owns seven original content, high definition networks, and owns and distributes over 32 television series, several of which have been nominated for and won Emmy Awards,” the story reports.
