Mary-Kate and Ashley Olsen were born on June 13th, 1986, in Sherman Oaks, CA. Their wealth came from acting in films, television and eventually in the apparel business. They started their career in acting at the age of 9 months on the T.V. sitcom, Full House. It lasted from 1987-1995. In the year 1993, they started their own company, Dualstar Entertainment Group LLC. It allowed them to produce the popular series The Adventures of Mary-Kate and Ashley and films made for television. Their franchise also sold a range of official products all over the world.
The fashionistas eventually entered the business community with their clothing lines called The Row and Elizabeth and James. They sell these exclusively through top-end retailers and famous Wal-Mart shops. When they reached 20, the fraternal twins presided over the tween retail empire called Dualstar Entertainment Group. They established it in 1993, and it now sells $1 billion worth of merchandise worldwide every year. It contains everything from hair-care products to videos from the twins’ website and Wal-Mart.
