In 1993, following Mary-Kate and Ashley's success on ''Full House'', a [[limited liability company]], [[Dualstar Entertainment Group]] was created to produce ''Mary-Kate and Ashley''-branded products. It produced a successful long string of [[Television film|TV movies]] and [[direct-to-video]] releases featuring the girls. They starred in ''[[Passport to Paris]]'' (1999), ''[[Switching Goals]]'' (1999),  ''[[Our Lips Are Sealed (film)|Our Lips Are Sealed]]'' (2000), ''[[Winning London]]'' (2001), ''[[Holiday in the Sun (film)|Holiday in the Sun]]'' (2001) and in the television series, ''[[So Little Time]]'' (2001–2002).

They became household names and popular figures in the [[preteen]] market during the late 1990s and early 2000s, with Mary-Kate's likeness seen in clothes, books, fragrances, magazines, movies, and posters, among others. There were fashion dolls of her made by [[Mattel]] from 2000 to 2005. They also starred in the films ''[[Getting There (film)|Getting There]]'' (2002), ''[[When in Rome (2002 film)|When in Rome]]'' (2002), ''[[The Challenge (2003 film)|The Challenge]]'' (2003) and made cameos in ''[[Charlie's Angels: Full Throttle]]'' (2003). In 2004, the twins appeared in their final and light-hearted romantic comedy film, ''[[New York Minute (film)|New York Minute]]''.

That same year upon their 18th birthday, both Mary-Kate and Ashley took control of Dualstar, becoming joint-[[Chief executive officer|CEOs]] and presidents of the company, which at the time had its merchandise being carried in over 3,000 stores in America and 5,300 stores worldwide.

These ventures, combined with an array of licensing deals for their names and likenesses, made Olsen wealthy at a young age. In 2004, Olsen's and her twin sister’s wealth was estimated at $137 million each.<ref>{{cite news|url=https://www.usatoday.com/money/media/2005-05-06-olsens-twins-business_x.htm|title=Billion-dollar teens take business seriously|newspaper=[[USA Today]]|date=May 6, 2005|access-date=June 18, 2012|first1=Jim|last1=Hopkins}}</ref>
