More than a half-dozen television networks, newspaper industry associations and advocacy groups have asked a federal judge in Washington to expand the media outlets on which tobacco companies are required to publish antismoking messages.

Under a settlement with the federal government, Philip Morris USA Inc., Altria Group Inc., R.J. Reynolds Tobacco Co. and Lorillard Tobacco Co. agreed to pay for messages on television, online, in newspapers and on cigarette packages detailing the health risks of smoking.
