Rather than utilize the routines his father developed, Blackstone developed his own and modernized his performance, though onstage he would, on occasion, perform a sequence of his father's illusions in a period setting.

Blackstone created four levels (beginner to advanced) of magic kits that were the best selling in the field.
In the early 1970s, he promoted a "PF Magic Wedge Kit" on a television commercial for PF Flyers sneakers, and he appeared on several commercials for Jiffy Pop popcorn.

In 1985, on the 100th anniversary of his father's birth, Blackstone donated to the Smithsonian Institution in Washington, D.C. the original floating light bulb — designed and built by Thomas Edison — and the original Casadega Cabinet, used in the "Dancing Handkerchief" illusion.
This was the first donation accepted by the Smithsonian in the field of magic.

Blackstone appeared as a guest on The Tonight Show, Donahue, The Today Show, Reading Rainbow and The Super Mario Bros. Super Show.
He also made occasional appearances as the mysterious Dr. Mephisto on the TV soap opera Santa Barbara.
Of his several TV specials, the PBS two-hour special was unique due to the intros by some of The Muppets.
Blackstone's PBS Square One TV, where he used magic tricks to teach mathematics to young people, was a favorite of his.
His recurring segment was known as "Backstage with Blackstone".

Blackstone designed the illusions used on SeaWorld's water show featuring the DC Comics superheroes.
They included The Joker cutting Batgirl up into multiple pieces, a variation of a classic multi-box illusion, and the first use in many years of the Jarrett pedestal to vanish Wonder Woman.

Blackstone and his wife Gay created and produced the special effects for "The Magic Summer Tour" for New Kids on The Block, as well as their "No More Games Tour".
He also did special effects for Alice Cooper, Michael Jackson ("The Victory Tour"), Earth, Wind and Fire, and Jane's Addiction with Perry Farrell.

During his career, Blackstone toured the U.S. extensively.
 Notably, his Magnificent Musical Magic Show played in 156 U.S. cities and Broadway.
It opened in May 1980, and played 118 performances.

Blackstone received the Academy of Magical Arts Magician of the Year Award in 1979 and 1985.

He performed at the prestigious FBI National Academy Association retrainer session in Chicago in 1980 where he was the featured performer at the formal closing banquet.

At the time of his death he was the most highly awarded magician of all time.
