Walt Disney Co. (DIS 0.94%) is arguably the most diverse, powerful, and beloved entertainment company on the planet. The company Walt and Roy Disney founded in 1923 has a $161 billion market cap, making it the 23rd largest company on the S&P 500 index. Disney's stock has returned 292% over the 10-year period through March 14, trouncing the broader market's 95% return and richly rewarding many investors.

Many of the company's impressive "firsts" and other interesting tidbits about it are fairly well-known. So, heigh-ho, heigh-ho, it's off to work I went until I was Sleepy digging up seven Happy facts that many of you might not know, not that I think you're Dopey. (Look for the other Dwarfs hidden in this article.) Enjoy!

1. Disney has claims to producing the first music video
Walt Disney's "Song-O-Reel," produced in 1923 when he was a 21-year-old living in Kansas City, Mo., is considered by some to be the first music video -- in very early form. Music videos would surge in popularity when MTV -- now owned by Viacom -- launched 58 years later in 1981.

Disney contracted with the Jenkins Music Co. to create a film illustrating the song Martha: Just a Plain Old-Fashioned Name, based on a song by a founder of the Coon-Sanders Original Nighthawk Orchestra. The film -- which Disney called a "Song-O-Reel" -- debuted at the Isis Theater in Kansas City. Martha was a silent film, but the Isis' organist Carl Stalling played the melody while the audience sang along using the words appearing on the film. Stalling would become Disney Studio's first music director.

2. A "Hidden Mickey" solar-power facility will soon help power Disney World
Disney World will soon be powered in part by a 5-megawatt solar-power facility Duke Energy (DUK -0.56%) expects to complete constructing this spring. It will be the largest solar facility at Disney World, with its power equivalent to about 1,000 typical residential solar rooftop systems. Duke Energy, the largest electric power holding company in the U.S., will own and operate the facility that will serve Reedy Creek Improvement District, the power provider to Walt Disney World.

In a whimsical twist, the facility's 48,000 solar panels on the 20-acre site are arranged in the three-circle silhouette of the head and ears of Mickey Mouse, as can be seen in the aerial view above, supplied by nearmap. "Hidden Mickeys" are everywhere at Disney's theme parks, such as in rock formations and the decor. 

3. The U.S. space program that put a man on the moon was partly inspired by a 1955 Disney TV show
During the mid-1950s, Disney collaborated with NASA rocket designer Doc Wernher von Braun to produce three educational films about space: Man in Space, Man and the Moon, and Mars and Beyond. By some reports, President Dwight Eisenhower called Disney to request a copy of Man in Space after it aired to show to top officials at the Pentagon. Even if this isn't true, NASA historians aren't Bashful about crediting the Disney-Von Braun collaboration with significantly influencing the development of the U.S. space program that put a man on the moon.

4. Disney had a lock on the most advanced Technicolor process for a period
Disney had exclusive use among animators of the then-most-advanced Technicolor process for producing color films for a certain period of time in the 1930s -- one year, according to the most reputable sources. Other animators -- who were surely Grumpy about this -- had to use either the older and inferior two-color Technicolor process or a competing process during this time. 

Technicolor, invented in Boston in 1916, wasn't the first process for producing color films, but its three-color process was superior at producing highly saturated colors. A Technicolor Motion Picture Corp. founder reportedly convinced Walt Disney to shoot the cartoon Flowers and Trees (1932) in the new process, which marked the first time a Disney animated short was made in color. This cartoon was also the first commercially released film to be produced in the new Technicolor process. Disney was wowed by the results and negotiated an exclusive contract for the use of the process. Disney's use of the process for The Three Little Pigs in 1933 excited audiences and Hollywood filmmakers alike -- and fueled a new and sustained boom in the production of films in color.

5. Disney has developed its own proprietary 3D printing technology
It's fairly well-known that Disney has been using 3D printing for various applications across its empire. In a popular 2013 attraction at its theme parks, for instance, visitors could be digitally scanned and have their likenesses put on a 3D-printed Star Wars' Stormtooper figurine. The technology is also used to produce unique costumes and props for films. The armor costume for Korath in Marvel's 2014 blockbuster Guardians of the Galaxy, for example, was printed using a Stratasys (SSYS 1.66%) Connex 3D printer.

It seems to fly under the radar, however, that Disney has developed its own proprietary 3D-printing technology. Its "Printed Optics" allows custom optical elements for sensing, display, and illumination to be directly embedded in the body of an interactive device. Disney has demonstrated the tech by 3D printing -- using a Stratasys Eden printer -- fiber optics to create animated eyes for interactive toys, though the technology's applications are potentially vast. According to Disney, "Printed Optics is part of our long term vision for the production of interactive devices that are 3D printed in their entirety."

6. Mr. Potato Head is the most advanced audio-animatronic character to date
The Mr. Potato Head located in Hollywood Studios' Toy Story Mania is reportedly the most advanced audio-animatronic to date. This is a simple example of Disney building upon its own technological achievements. Disney debuted the first audio-animatronics at the 1964 World's Fair in New York. It was at this event that IBM introduced many consumers to computers and Ford Motors unveiled the now-iconic Mustang. Yet, Disney's "talking robots" -- including Abraham Lincoln and It's a Small World -- were reportedly the biggest hit among many fairgoers.

Related tidbit: Mr. Potato Head, first manufactured in 1952 by Hasbro (HAS 1.37%), was the first toy advertised on television. Hasbro today sports close ties to Disney, which has helped power its stock to superior gains in recent years. Among other ties, Hasbro holds a license to produce Star Wars-themed toys and the exclusive rights to develop dolls based on Disney Princess characters. 

7. Lillian Disney came up with the name "Mickey Mouse"
Many Disney aficionados likely know that Walt's wife, Lillian, came up with the name "Mickey" in 1928 for the cartoon mouse that vaulted Disney Studio to world fame. This one seems worth including, however, to underscore that it's wise to surround yourself with smart and supportive people in order to not only be successful, but also happy. This description reportedly fit Lillian Bounds Disney, who Walt hired as an ink artist for his then-fledgling Disney Studio in 1923 and married two years later.

In short, Disney is not a company investors should bet against.
