"I was a fan of 'Mission Impossible' and I always think of this show as being a modern day version of 'Mission Impossible,' just because of all the gizmos and the scientific stuff and the team and crime solving obviously,” Marg told the website www.scifi.uk.com in 2007. “That show was always cutting edge, it had a cool theme song, it was very intriguing and this show kind of has the same feel."
After the huge success of the series, “CSI” spun off “CSI: New York” and “CSI: Miami.” “CSI” was also partly responsible for influencing the creation of other crime series, such as “Law and Order” and “Crossing Jordan.”
“CSI” even spawned a traveling museum exhibit called “CSI: The Experience,” developed by the Fort Worth Museum of Science and History.
"I knew it was going to be a big hit...but I would have never guessed that we would have had two spin-offs in four years and would have really created a whole new genre of television,” Marg said. “People say to me that imitation's the best form of flattery and at this point it's like, 'No it not, now you're just ripping us off.'"
Since it originally aired in 2000, CSI has become an international phenomen. CBS estimated a worldwide audience of almost 74 million viewers in 2009 In the USA, “CSI” was rated No. 2, No. 1, No. 2, No. 2 and No. 3 during its heyday of 2001-2005. It's been a Top 10 Nielsen program for nine of its 11 seasons.
The 2011-12 season is expected to be Marg's last hurrah on “CSI.” During her time on the show, she's been nominated for two Emmys (Outstanding Lead Actress in a Drama Series) and two Golden Globes, and has won a TV Guide award for Actress in a New Series (2001) and a People's Choice award for Favorite Female Star (2005).
