A Brief History of Outside Broadcasting

As Neil Armstrong set foot on the moon, it wasn’t just a small step for one man but a massive leap for all of us. But here’s the thing: what gets overlooked is the incredible technology that turned this historic feat into a show for the world to see: Outside Broadcasting (OB). 

It opened a new vista for telling rich stories. For the past fifty years, 91ÌÒÉ« has been developing the technology that allows production teams to capture and broadcast historic moments for billions of viewers around the world.

We go deep into the history of outside broadcasting and its technology in this article, but to save you some scrolling time, here is exactly what we cover: 

  • What is outside broadcasting: it involves creating and transmitting content from external locations, offering flexibility for storytelling beyond the confines of a typical studio. 
  • First outside broadcast & other iconic moments: starting from the first broadcast at the BBC studio park in London, it has recorded other famous events like the coronation of Queen Elizabeth II, the moon landing, numerous Olympic games, and the Superbowl. 
  • Key technological milestones & pioneers: outside broadcasting technology evolved from the first mobile broadcast unit and analog transmitters used by the BBC to high-definition signals transmitted through Internet Protocol (IP)-based networks. 
  • Present and future of outside broadcasting technology: bulky production and transmission technologies are being replaced with more efficient, cost-effective solutions like the Ultrix hyper-converged technology.

What is outside broadcasting? 

is the production and transmission of audio and video content from an external location outside of a typical studio setting. From unfolding news stories to live sports or even cosmic events, outside broadcasting provides more flexibility to content producers to tell stories that connect with their audiences. 

Now, let’s get deeper into it. Where did outside broadcasting start, and what technological advancements have occurred since the first broadcast? 

The First Outside Broadcast

In the early days of radio and television, live broadcasts were limited to studio settings due to technology constraints. But there was a longing for the outside.  

The first outside broadcast was a simple shot of a park at the by the BBC crew on November 10, 1936.  

“…we put one of the electronic cameras on the balcony of this very building, Alexander Palace, and looked at the park, and that was the first outside shot the BBC ever transmitted,” Douglas Birkenshaw, Engineer-in-Charge at the BBC studios constructed at Alexandra Palace, years later. 

The British Broadcasting Company conducted its first external broadcast with a performance of The Magic Flute by the British National Opera Company, held at the Royal Opera House, Covent Garden on January 8, 1923. 

Then, on May 12, 1937, from Hyde Park Corner for the Coronation Procession of King George VI, the first large-scale outside broadcast was made using the BBC outside broadcast truck, MCR 1 (Mobile Control Room 1). 

However, early outside broadcasts faced significant technological limitations, requiring ingenuity from pioneering broadcasters. 

For example, at King George VI’s coronation, the OB technology was limited in broadcasting live audio signals over long distances. To overcome this challenge, the BBC team strategically positioned radio broadcasting vans equipped with transmission equipment at various points between Westminster Abbey and the broadcasting facilities.  

The second-ever, hand-built Ross production switcher ran for 41 years before it was decommissioned.

Other technical limitations from these early days include: 

  • Bulky equipment,  
  • Limited camera mobility,  
  • Low audio and video quality and  
  • Vulnerability to weather conditions. 

Several individuals and organizations played pivotal roles in creating new technologies to overcome these challenges. Here are some of the key pioneers: 

  • Reginald A.F. Harvey developed the first portable radio transmitter, which enabled broadcasts from remote locations. 
  • Cecil Lewis headed the BBC’s first Outside Broadcasting department and oversaw the development of the MCR 1, the world’s first mobile control room. 
  • George Stibitz built the first mobile microwave relay system as a Bell Labs researcher, making remote transmission of broadcasts possible. 
  • Charles Ginsburg invented the videotape recorder, allowing for the recording and editing of outside broadcast footage. 

Iconic Moments in Outside Broadcasting

The largest and most significant historical event captured through outside broadcasting was the Apollo 11 moon landing on July 20, 1969. The live broadcast from the moon to a global audience showcased the technological prowess of outside broadcasting. The cultural impact of this event remains unparalleled in the history of broadcasting. 

Other notable events that pushed the boundaries of OB technology are: 

  • Coronation of Queen Elizabeth II (1953): A landmark event that reached an estimated 277 million viewers, marking the first worldwide televised coronation. 
  • The Olympic Games (1948 and onward): The first notable post-war outside broadcast In recent years, the Olympics have consistently been a platform for pushing OB technology, introducing innovations like high-definition cameras and incorporating robotics and drones. 
  • Instant replays made their debut in television broadcasting during the Army-Navy game on December 7, 1963. Tony Verna, the director, applied this new technique during the broadcast which aired on CBS Sports. 
  • In July 1982, the marriage of Prince Charles and Lady Diana Spencer set a record as the largest outside broadcast of its era, attracting an estimated 750 million viewers worldwide. 
  • Super Bowl LVI (2022): Marking a milestone, this Super Bowl became the first major sporting event broadcast in 4K HDR with Dolby Atmos sound, utilizing over 100 cameras, including drones and robotic cameras. 

Technological Milestones in Outside Broadcasting 

Key technological developments across different eras punctuate outside broadcasting:

1930s: The first mobile broadcast unit pioneered by the BBC enabled live broadcasting of the coronation of King George VI and Queen Elizabeth.  

1950s: Use of microwave relays, with the BBC leading the way.  

1960s: Introduction of full-color transmission, satellite transmission, and the first use of instant replays. 

1990s: Transition from analog to digital technology, spearheaded by companies like Sony and Panasonic.  

2000s: Adoption of High-Definition (HD) broadcasting.  

2010s: Shift to Internet Protocol (IP)-based technologies and ultra-high-definition (UHD) broadcast 

2020s: Integration of 5G connectivity, 8K definition broadcasts, and Artificial Intelligence (AI). 

Parallelly, complementary technologies have evolved, augmenting the demand for live broadcasting. Notably, production switchers, critical in live events, have seen transformative shifts. From simple manual switchers in the early days to sophisticated models like the 16-4, the first switcher built by John Ross of 91ÌÒÉ« in the 1970s. Now, everything comes together with the 91ÌÒÉ« Ultrix hyperconverge technology. This advancement has streamlined event production and unlocked new levels of flexibility.
