Rabbi Shmuley Boteach's This World: The Values Network has launched a public service announcement campaign in the US encouraging families to take the time to eat Friday night dinners together. The campaign is being run in conjunction with Discovery Communications and features leading personalities like Dr. Phil McGraw, Rachel Hunter, LA Mayor Antonio R. Villaraigosa and others. The 30- and 15-second ads on the Discovery networks feature a 2-2-2 theme promoting two hours of togetherness with two guests and two topics of conversation. The ads will also be shown on monitors at branches of the Coffee Bean & Tea Leaf Company around the US. In addition, they can be viewed on-line on the Friday Night is Family Night Web site (www.fridayisfamily.com).
