She immediately landed the co-host spot on the NBC pilot "Roadshow" with John Candy, Julie Brown and Rick Overton. The show was intended as a replacement for "Saturday Night Live" during a ratings dive. Plans for the show were scrapped when Fred Silverman, the producer and a major proponent of the show, left the network. Disappointed, but undaunted, Greta began to guest star on numerous television shows. In commercials, she starred as the Mauna Loa Macadamia Nut girl and the bathing beauty for Eclipse sunscreen commercials.

Greta was featured in the super popular sci-fi mini-series "V: The Final Battle" as Lorraine, a good lizard. Even now Greta is frequently invited to sci-fi conventions where there are actually people dressed as her character, complete with blonde hairdo and nuclear encoder. Greta garnered much attention in the hit movie "48 Hrs." and as Jennifer, the hardhat on Dex's oilfield on "Dynasty" where her character had run-ins with Joan Collins' "Alexis". Greta has guest-starred on most top television shows, including, most recently, "Lois and Clark".

Greta has found a way to indulge her notoriety as an actress, love of physical fitness, and her schooling in communications and is bringing the message of health and fitness to the people of America. She was Editor-In-Chief of Natural Body and Fitness Magazine from 1988-1990. During that time she co-founded Fitness Against Drugs, an anti-drug foundation that promotes physical fitness as an alternative "hip" lifestyle for teens. FAD's message to kids is that it's not cool to be a gang member, drug user or school dropout. By using celebrity role models who advocate a healthy lifestyle, FAD gets a positive message across to kids. She has served as Editor of California Health Magazine, a health supplement to the LA Times sponsored by a large group of independent pharmacies bringing health and information to the Southern California public.

She is currently the founding Editor of Ms. Fitness Magazine. Ms. Fitness promotes physical fitness to women across the world and is "sister" to the widely televised Ms. Fitness USA specials. As a proponent and judge of these contests, Greta serves as an ambassador of health and fitness to females of all ages and backgrounds. One of her unofficial roles in this capacity is to encourage women to adopt healthy eating and training habits and to avoid eating and other emotional disorders.

As a writer on health and fitness issues, Greta has covered topics ranging from ways to help prevent breast cancer to eating disorders to high-tech strategies for fat-burning. She co-authored the book "Cory Everson's LifeBalance" and is currently working on a FITCAMP scrapbook and recipe file, which will be published soon.

The FITCAMP book comes out of Greta's work as Founder/Director of Greta Blackburn's FITCAMPS, which take place in Malibu, Maui, Mexico, Canada & Australia (soon) and serve as training symposiums for fitness professionals and other interested men and women from all over the world. Seminars include information on training, nutrition, disease prevention, longevity and other valuable health topics.

Her charitable work involving fitness includes production and creation of several televised celebrity sports events, including the Pro-Celebrity Sno Games benefiting the National Multiple Sclerosis Society; the Pro-Celebrity Winter Games benefiting the Special Olympics; the Tennis Tournament of the Stars benefiting the Make-A-Wish Foundation and the BBB Benefit for the Sacramento Police Widows and Orphans Fund. Blackburn, forty-something herself, is also at the vanguard of a burgeoning "Fitness after 40" trend that keeps her busy with speaking engagements and appearances.

Greta has been called "The Most Glamorous Editor In The World", due in part to her appearances on "Entertainment Tonight", "EXTRA", "Hard Copy", "Good Day LA", "Terry Bradshaw's Home Team", "The Home and Family Show", "Crook & Chase" and dozens of other television and radio shows. She appears this season as the health and fitness expert for the Home & Garden Channels "Smart Solutions". She is a triathlete and also has a green belt in Tae Kwon Do.

Greta also works as a consultant to hotel chains in developing their fitness programs and spas. "Greta Blackburn's Fitstops" are published internationally and are travel reviews featuring resorts with fitness facilities. She is also a spokesperson for Great Earth Vitamins. She has served on the City of Hope's special advisory board to their "Workout With The Stars Against Aids" and has produced a pamphlet for the Los Angeles Times' California Health supplement called "The Safe Six For Safe Sex" as a free public Aids awareness brochure. She is a founding member of Southern Touch Food Products Health Council, a member of The American Association of University Women, and has been featured in the Who's Who of American Women.
