Smoking kills an average 1,200 Americans daily, US tobacco companies admitted Sunday in court-ordered "corrective statements" published in newspapers.

The ads began appearing 11 years after District Judge Gladys Kessler, in a 1,682-page opinion, ruled in 2006 that the companies violated racketeering laws by deceiving the public for decades on the health dangers of smoking.

She ordered them to publish corrective statements on five health topics, but the exact wording of those statements was held up pending tobacco company litigation.

In 2014 the companies and the government reportedly reached agreement that the ads would be published in major Sunday newspapers as well as on prime-time television for a year, and elsewhere including on cigarette packages.
