In 1921, they called it “the largest audience in history,” the 300,000 or so people estimated to have heard one of the first radio broadcasts of a special event — the outdoor heavyweight championship boxing match between American Jack Dempsey and French challenger, Georges Carpentier. Dempsey was reigning world champ at the time, and Carpentier was a European boxing champion and decorated French Army veteran. The fight’s promoter had billed the event as the “Battle of the Century.”
A hastily assembled outdoor arena was built on a farm in Jersey City, New Jersey, not far from New York City. More than 80,000 fans came to see the fight in person on July 2, 1921, producing boxing’s first million-dollar gate. Dempsey won in four-round knockout in a scheduled 12-round fight. But the big news for many was the radio broadcast of the fight. It was the first ever broadcast to a “mass audience,” with the blow-by-blow call of the fight from ringside relayed over the new “radiophone,” reaching hundreds of thousands in the northeast U.S. Wireless Age magazine, reporting on the event a few weeks later, described the fight’s call over radio by “a voice that sounded loud and clear throughout the Middle Atlantic states.” It was “history in the making,” said the magazine.
“Hero” vs. “Slacker”
There was also a good deal of hype associated with this fight, as there would be for any major event of this kind. The promoter of the fight, Tex Rickard, cast its principal contestants as “hero” vs. “villain.” The “hero” in this case was not the American Jack Dempsey, but the Frenchman, Carpentier, the light-heavyweight champ who had distinguished himself as a pilot in World War I. Dempsey, on the other hand, was cast as the “villain” as he had been labeled a “slacker” for avoiding the military draft — even though he had been found not guilty of the offense in 1920. Promoter Rickard offered Carpentier $200,000 for the fight and $300,000 to Dempsey — considerable sums for the time — as well an equal share of 25 percent of the film profits. Rickard saw the radio broadcast of the fight as a positive for his future business, and he did what he could to accommodate the new technology at the site. He believed that radio might be a way to advance prizefighting in the post-World War I popular culture. Rickard allowed for a makeshift wooden room for the radio broadcast to be constructed under the stands. Telephone lines and a temporary radio transmitter, sponsored by the Radio Corporation of America (RCA), were installed at the Delaware, Lackawanna and Western Railway terminal in Hoboken, New Jersey.
Radio beyond the reach of a few people had barely begun in the early 1920s. Fledgling operations had started in 1916 in both New York city and Pittsburgh, Pennsylvania. In Pittsburgh, a Westinghouse employee named Frank Conrad began sending out recorded music played from a phonograph over a radio transmitter set up in his garage. By 1920, Conrad’s employer, Westinghouse, noticed that the broadcasts had increased the sales of radio equipment, which Westinghouse was then manufacturing. The company had Conrad move his transmitter to the Westinghouse factory roof. Westinghouse then applied for a government license and started the pioneer station KDKA, which in early November 1920, began radio programming with the Harding-Cox Presidential election returns. Those broadcasts, however, were only reaching a few thousand hobbyists.
In New York City, too, local radio broadcasts had begun in the fall of 1916 over Lee DeForest’s experimental “Highbridge” station. David Sarnoff, a manger at the American Marconi telegraph company, who lived in New York had heard the early Highbridge broadcasts. Sarnoff wrote a brief memo to the Marconi’s president in 1916-17 about a business possibility for developing a “radio music box” to sell to amateur radio enthusiasts. But nothing came of Sarnoff’s idea at the time. Marconi was then in the heat of WWI. A few years later, however, in January 1920, the Radio Corporation of America (RCA) was established when General Electric acquired American Marconi and Sarnoff, with it. RCA had formed in 1919 after the U.S. Government relinquished control of the wireless industry following World War I.
“Radio Box For Entertainment”
David Sarnoff, meanwhile, wrote another, more detailed memo on the prospects for radio business and sales to the general public — a 28-page memo titled Sales of Radio Music Box for Entertainment Purposes. “I have in mind a plan of development which would make radio a ‘household utility’ in the same sense as the piano or phonograph,” Sarnoff began. “The idea is to bring music into the house by wireless,” by which he meant radio. Sarnoff saw a large potential market, which he then put at about 7 percent of the total families,” yielding a gross return of about $75 million annually in 1920s dollars. Both estimates would soon prove to be very conservative. “Aside from the profit to be derived from this proposition,” he wrote, “the possibilities for advertising for the company [RCA] are tremendous…” The company’s name “would ultimately be brought into the household,” he said, and radio thereby would receive “national and universal attention.” Indeed it would, and did. But it was the broadcast of the Dempsey-Carpentier fight that would help spark the early public curiosity in the radio and also help the rise of RCA and the radio business. RCA, in fact, made its broadcast debut with the July 2, 1921 championship fight.
Sarnoff also appears to have played an important role in the radio broadcast of the Dempsey-Carpentier fight, although some say the extent of his role has been exaggerated. Still, it does appear that Sarnoff helped make the broadcast possible: he provided money for expenses, a high-powered GE transmitter, and the use of the Lackawanna Railroad terminal antenna in Hoboken, New Jersey. There are also varying accounts as to who initially came up with the idea to do a wide-area radio broadcast of the fight, with some attributing the idea to Sarnoff, and some to others. Julius Hopp, manager of the Madison Square Garden concerts at the time, had observed amateur radio men in more limited venues and was impressed with their descriptions by voice. Some credit Hopp with the idea. In any case, in April 1921, it appears the idea of broadcasting the Dempsey-Carpentier fight was offered to promoter Tex Rickard and his partner, both of whom liked the idea. There had also been one previous fight broadcast on radio in the Pittsburgh area in April 1921, heard only by a limited number of listeners and radio hobbyists in that location. The broadcast that planners had in mind for the Dempsey-Carpentier fight, however, was for a much broader region.
An early July edition of Wireless Age magazine described the plan for how the broadcast would work:
…The radio station at Hoboken will be connected by direct wire to the ringside at Jersey City, and as the fight progresses, each blow struck and each incident, round by round, will be described by voice, and the spoken words will go hurtling through the air to be instantaneously received in the theaters, halls and auditoriums scattered over cities within an area of more than 125,000 square miles.
Through the courtesy of Tex Rickard, promoter of the big fight, voice-broadcasting of the event is to be the means of materially aiding the work of the American Committee for Devastated France [i.e., following World War I] and also the Navy Club of the United States. These organizations will share equally in the contributions secured by large gatherings in theaters, halls and other places. The amateur radio operators of the country are to be the connecting link between the voice in the air and these audiences. … Any amateur who is skilled in reception is eligible, whether or not he is a member of any organization.
On fight day, a notable cast of local and national dignitaries attended the actual event in person. Among politicians and celebrities who joined the 80,000-to-90,000 fans who came to watch the fight were: industrialists John D. Rockefeller, Jr. William H. Vanderbilt, George H. Gould, Joseph W. Harriman, Vincent Astor, and Henry Ford; entertainers Al Jolson and George M. Cohan; literary figures H.L. Mencken, Damon Runyon, Arthur Brisbane, and Ring Lardner; the three children of Theodore Roosevelt — Kermit Roosevelt, Theodore Roosevelt, Jr. and Alice Roosevelt Longworth; prominent Long Island residents, such as Ralph Pulitzer, Harry Payne Whitney and J.P. Grace; Jersey City Mayor Frank Hague; and New Jersey Governor Edward I. Edwards. At the gate, meanwhile, the fans who poured in payed a then-record $1,626,580. It was the first time that a million-dollar amount had been exceeded for a boxing event.In addition to those assembled at the fight location in New Jersey, tens of thousands gathered in various public venues — bars, restau- rants, theaters and halls where ham operators or radio hook-ups had been made. Among such locations, for example were: Loew’s New York roof top at Broadway & 45th St. where some 1,200 were assembled; Colonial Hall in Bridgeport, Connecticut where an audience of 500 enjoyed the returns courtesy of the Bridgeport Radio Club; some 570 listened to the fight at The Playhouse in Wilmington, Delaware — and at hundreds of other such places. In Times Square, New York a huge throng of some 10,000 people gathered outside the New York Times Building to hear marquee-posted updates of the fight that were relayed to the crowd. By fight time, the anticipation and build-up for this fight was sky high. In addition to Rickard’s promotion, famous writers such as George Bernard Shaw chimed in. Shaw claimed that Carpentier was “the greatest boxer in the world” and suggested that the odds should be placed 50-to-1 against Dempsey. But the match turned out to be less of a contest than many assumed it would be, as Dempsey dominated — but not a first. Carpentier got off to a fast start and hit Dempsey hard in the first round, and again with two hard shots to the head in the 2nd round, stunning the champ. One reporter at ringside, however, noted a furious comeback by Dempsey with a flurry of punches, still in round 2. Carpentier broke his thumb when he hit Dempsey in the 2nd. In the next round, the bigger, stronger Dempsey began to get the best of Carpentier, punishing him on the ropes. In round 4, the Frenchman was knocked down once, and then again for the ten-count. Dempsey won. But in an interesting gesture of kindness no doubt rarely seen in a boxing ring, Dempsey moved to help his opponent to his feet and to his corner at the fight’s end.
The results of the fight were big news all across the country in the next day’s newspapers — including the fight’s astounding $1.6 million gate. Some historians, in fact, see the fight as a key landmark for the Golden Age of sport that boomed during the 1920s; a Golden Age that also brought expanded media coverage and business promoters like Tex Rickard into the arena, setting sports media on the path to big-business entertainment. As for radio, other sports broadcasts followed. By August 5th, 1921, the first broadcast of a baseball game was made over Westinghouse station KDKA — a game between the Pittsburgh Pirates and the Philadelphia Phillies from Forbes Field in Pittsburgh. Demand for home radio equipment soared that winter. By the spring of 1922, David Sarnoff’s prediction of popular demand for broadcasting was coming true, and over the next eighteen months, he and RCA gained in stature and influence. RCA soon went into cross-licensing arrangements with AT&T and Westinghouse, which helped propel the company into a leadership role in both the broadcasting and recording industries.By 1922, there were 30 radio stations in America, and things picked up considerably after that. By late January 1923, programming from New York’s WEAF station was being carried simultaneously over a second station WNAC in Boston, giving rise to the concept of the “network” or “chain broadcasting.”
Less than a month later, on February 2nd, a transcontinental network broadcast link was formed between WEAF in New York and KPO, San Francisco, which was the Hale’s Department Store station. Although New York’s WEAF had featured one of radio’s first paid advertisements in August 1922 — by the Queensboro Corporation using a ten-minute pitch to advertise a new real estate development — broadcasting was not yet supported by advertising.
Most of the early stations were owned by radio manufacturers, department stores trying to sell radios, or by newspapers using them to sell newspapers or express their owners’ opinions.Still by 1923, the number of stations had grown to 550 and about 3 million people had access to some kind of radio, many using crystal sets with earphones to receive news, bulletins and music. Radio programming soon expanded to the stock market, weather reports, comedy shows, music broadcasts, and more. In the fall of 1923, another sporting event — baseball’s World Series games between the New York Yankees and the New York Giants — helped boost radio again, making a big impression on many listeners, as a former concert singer by the name of Graham McNamee began doing the game’s play-by-play in a colorful and enthusiastic announcing style on New York’s WEAF. McNamee thereafter became one of radio’s first broadcast personalities. In 1926, RCA purchased its first radio station, WEAF in New York it also launched the National Broadcasting Company (NBC), the first radio network in America. Four years later, David Sarnoff had become president of RCA and NBC.
Radio historians mark the July 1921 Dempsey-Carpentier fight as one of the landmark events advancing the “radio era” and big-audience communication. And as would become the pattern for other communications technology in the future — whether the Muhammad Ali vs. Joe Frazier fight by satellite TV in 1975, or subsequent global telecasts of World Cup Soccer, Superbowl games, or the Olympics — big sporting events would often be used to introduce or showcase new technology or expanded capability, reaching not just hundreds of thousands, but hundreds of millions and billions. The 2008 Olympics in Bejing, for example, had an estimated total audience of some 4 billion viewers. Special, multi-venue rock concerts and global charity events can now reach billions as well. And online communications only add to these numbers. Still, it wasn’t that long ago when our communications world was a lot smaller; when “big” was a few hundred thousand, as it was on that day in July 1921 when the human voice beamed out over the northeast United States.Other boxing-related stories at this website include: “The Rocky Statue, 1980-2009,” on the 20-year controversy in Philadelphia over the Rocky Balboa statue, and, “Philadelphia Morning,” featuring Bill Conti’s film music as critical to the success of the first Rocky film of 1976-1977.
