Millions of Americans are celebrating the annual Thanksgiving Day holiday with a traditional feast with family and friends. Thanksgiving, held in the United States on the fourth Thursday of November, is one of the biggest travel holidays of the year. The day centers on a meal typically including turkey, potatoes, stuffing, cranberry sauce and pumpkin pie. The first official Thanksgiving was observed in 1863, although some believe the original holiday dates back to 1621. That year, British colonists at the Plymouth settlement in what is now the northeastern state of Massachusetts held a feast with the Wampanoag Native American tribe, who taught them how to grow food and hunt for game in their new home.  President Barack Obama released his weekly address Thursday, in honor of the holiday. He called on Americans to come together and support each other as the country struggles with war and unemployment. The president said he hopes Democrats, Republicans and Independents can work together during the coming months to make progress on the economy and other issues. In addition to the traditional Thanksgiving feast, many Americans will spend the day watching nationally-televised events such as New York City's annual Thanksgiving Day parade, sponsored by Macy's department store, which includes musical performances, elaborate floats and giant inflatable cartoon characters. The Friday after Thanksgiving, known as "Black Friday," is seen as the start to the holiday shopping season, with many stores offering big discounts and opening in the pre-dawn hours for a rush of shoppers. .
