How MGM Became the Biggest Studio in Old Hollywood


How MGM Became the Biggest Studio in Old Hollywood


   ❝ The Studio That Defined Hollywood’s Golden Age ❞

When most people think about the Golden Age of Hollywood, an iconic image immediately pops in their head: a roaring lion inside a film reel

For decades, that lion represented Metro-Goldwyn-Mayer, more widely known as MGM—the studio that dominated Hollywood during the 1930s and 1940s. It homed some of the world's most well known movie stars, producing many of the era's most famous films, and became one of the most financially successful entertainment companies in American history.

But MGM did not become Hollywood's most powerful studio by mistake.

Beyond the fancy movie premieres, dazzling costumes, and famous actors was a carefully designed business empire built through smart leadership, long-term planning, and huge investments in talent and production.

The Creation of MGM

Before MGM existed, Hollywood's entertainment industry looked very different.

During the early 1920s, countless film studios competed for audiences, but many struggled to keep consistent profits.

Meanwhile, theater owner Marcus Loew had created one of the biggest theater chains in the United States. However, despite owning hundreds of theaters, Loew still depended on outside studios to make films for his audiences. He realized that having authority over both film production and distribution would give him a huge advantage.

Instead of continuing buying movies from other companies, Loew decided to own the studio that created them.

In 1924, he combined three companies—Metro Pictures, Goldwyn Pictures, and Louis B. Mayer Pictures—to create Metro-Goldwyn-Mayer. Instead of making a company from scratch, MGM immediately launched with experienced employees, established production facilities, successful actors, and a nationwide distribution network already set in order.

From the beginning, MGM was built to succeed.

The Men Who Built the Studio 

Although Marcus Loew started MGM, two men were largely responsible for transforming it into Hollywood’s most successful studio: Louis B. Mayer and Irving Thalberg.

Louis B. Mayer

The most prominent figure in MGM was Louis B. Mayer, who became one of the most powerful executives in the history of Hollywood. His official title within MGM was actually vice president, but he held the most authority within the company from its creation in 1924, until he departed in 1951.

Mayer understood that viewers desired films that felt glamorous, hopeful, and engaging. During some of the most hardest times in America, including the Great Depression and World War II, movies served as an escape from the everyday struggles Americans endured.

Mayer valued the belief that audiences were not simply buying tickets to watch stories—they were buying dreams.


Irving Thalberg

The second key figure behind MGM’s success was Irving Thalberg, who led the studio’s production.

Thalberg was just 24 years old when he joined MGM! Despite his young age, he quickly proved himself to be one of the most talented creative executives to come out of Hollywood. Although he was just in his early 20's, he possessed an extraordinary understanding of storytelling and audience expectations.

He was carefully persistent in reviewing scripts before production began, he demanded rewrites when needed, and he regularly ordered scenes to be reshot if early audiences reacted in an negative manner. His huge success and young age later earned him the nickname “The Boy Wonder.”

Unlike Mayer, who focused heavily on business and publicity, Thalberg valued the creative aspect of creating films. His perfectionism turned out to be one of MGM's greatest strengths.

Together, Mayer’s business instincts and Thalberg’s creative eye became one of MGM’s greatest competitive advantages.

One of MGM’s greatest competitive advantages was not its cameras or its studios—it was its stars.

In the modern show business, it is normal to see actors work with multiple studios throughout their careers. However, during the Golden Age of Hollywood, the opposite was the case. Performers were mandated to sign long-term contracts that gave studios huge amounts of control over their careers and personal lives.

MGM took complete control of this system.

The studio had authority on almost every aspect of its performers’ professional careers, including the roles they played, their public images, their personal relationships, and even diets.

Although MGM placed extremely harsh restrictions on actors, they somehow created some of the greatest movie stars in history.

Judy Garland, in particular, later spoke about the difficult conditions she experienced while working under MGM as a young performer, revealing the intense pressure placed on stars behind Hollywood’s glamorous image. 

"They'd give us pills to keep us on our feet long after we were exhausted... Then they'd take us to the studio hospital and knock us out with sleeping pills..." (said in a 1957 interview with McCalls magazine).


MGM’s Legendary Stars 

MGM’s legendary lineup included names such as:

 Clark Gable, Greta Garbo, Joan Crawford, Judy Garland, Gene Kelly, Spencer Tracy, Mickey Rooney, Jean Harlow, Myrna Loy, and Elizabeth Taylor.

A common misconception is that MGM simply hired talented actors.

In reality, the studio carefully created celebrities.

The level of control studios held over actors was extremely damaging, but it also created the illusion that these stars were not ordinary people—they were glamorous, larger-than-life figures who seemed almost otherworldly. 

Eventually, MGM adopted one of the most famous slogans in Hollywood history:

“More Stars Than There Are in Heaven.”

It sounded like a typical, exaggerated advertising slogan, but considering the immense amount of legendary performers under MGM’s contract, many audiences believed it was true.


Quality Over Quantity 

Unlike many competing studios, MGM built its reputation by producing movies that appeared more lavish, remarkable, and striking than those of its competitors. 

The studio invested large amounts of money in detailed costumes, huge sets, thorough production designs, and the most talented directors, writers, and cinematographers of Hollywood.

MGM executives believed moviegoers could spot the difference between an ordinary film and a magnificent one.

If an MGM film looked bigger, brighter, and more put together than its rivals, audiences wouldn't stop buying tickets.

Their plan turned out to be a huge success.


 Hollywood’s Greatest Productions 

 Movies such as:

The Wizard of Oz (1939)



Meet Me in St. Louis (1944)



An American in Paris (1951)



Singin’ in the Rain (1952)



Ben-Hur (1959)

became some of the most celebrated films in the history of cinema.


However, MGM’s commitment to quality also came with serious financial risks.

The Wizard of Oz, for example, went through tons of production issues, including changes in directors, script rewrites, and worries about its increasing budget.

A lot of executives had big concerns that the large cost of the fantasy film would fail to recover its costs.

But to their surprise, the movie ended up becoming one of the most loved movies ever created and a iconic representation of the Golden Age. 

Competition Was Fierce 

Although MGM was considered the most powerful studio in Hollywood, it wasn't prone to rivals.

Every major studio had its own identity and strengths.


Hollywood’s Great Rivals 



Paramount Pictures

became known for sophisticated dramas, glamorous stars, and gorgeous productions.

Warner Bros.

built its reputation through socially complex stories, crime stories, and gangster films.

20th Century Fox

became famous for their musicals and the popularity of child actress Shirley Temple.

RKO Pictures

created huge box office hits, like King Kong (1933) and Citizen Kane (1941).


Every studio had something different to offer.

However, MGM consistently remained one of the most profitable studios because it successfully combined three powerful advantages:

✦ unmatched star charisma 
✦ high-quality productions
✦ strong business planning


 The Numbers Behind MGM’s Success 

Towards the late 1930s, MGM had grown into one of the biggest entertainment operations across the globe.

The studio employed thousands of people, ranging from actors and directors, to  writers, musicians, editors, costume designers, painters, carpenters, electricians, and many other workers required to create a Hollywood production.


 The MGM Studio Empire 

The MGM studio lot in Culver City, California, covered about 185 acres of land (approximately 140 American football fields!) and contained enormous sound stages, streets, offices, and well planned sets that could change into almost any location.

At the peak of MGM, they created over dozens of movies every year. Their goal was to produce 1 movie each week, but they would usually end up releasing a new movie every 9 days.

The company brought in millions and millions of dollars of profit. The largest amount of revenue they brought in a year was $9.5 million in 1939 (about $228.3 million today!) 


For millions of Americans, going to an MGM movie became more than simple entertainment—it became a daily ritual.

The studio didn't simply sell films.

They sold glamour, excitement, and an escape into another world.


Why MGM Lost Its Dominance 

No company stays at the top forever.

Post World War II, Hollywood began facing major changes.

Movie attendance started to decline because American households started to purchase televisions, finding newer and easier ways to experience entertainment from home.

Then, in 1948, the United States Supreme Court issued the Paramount Decision, declaring that major film studios could no longer own theater chains and control both the production and exhibition of movies.

This decision mandated huge companies like MGM to separate their filmmaking operations from their theater businesses, putting an end to the biggest advantage that had helped studios dominate Hollywood for years.

During this time as well, audiences started searching for different kinds of movies as well. 

Viewers desired a wider range of stories, and the traditional studio system slowly began to disappear.

Actors gained more freedom to work with other companies instead of being forced into long-term studio contracts.

Solo filmmakers became more influential, and Hollywood entered a new era.

Although MGM continued producing successful films, it was no longer the unstoppable force it had been during the Golden Age.


MGM’s Legacy

Even though MGM’s period of dominance eventually ended, its impact on Hollywood remains undeniable.

The studio helped master the star system, showing the power of investing in high-quality productions, showing that strong marketing could create lasting loyalty from audiences. 


The iconic MGM lion logo is still one of the most recognizable symbols in show business, and despite several of their movies being released almost a century ago, MGM's films are still watched today by thousands of movie lovers across the world.

When historians take a look back at Hollywood’s Golden Age, MGM is often remembered as the studio that defined the era.


For over two decades, no other studio compared to MGM’s mix of talent, ambition, financial success, and cultural influence.

The story of MGM is not just the story of a movie studio.

It is the story of how smart business moves, influential leaders, and persistent  investment turned a company into one of the most amazing entertainment empires in history.
