The Podcasting Boom Explained in One Infographic
The impact of technology on how we consume information cannot be understated.
The most seismic shift has been to the media landscape as platforms like Facebook overtake traditional channels of news, distribution, and advertising. Not only does this put incumbent news conglomerates in an unenviable position, but it has also thrust tech companies into the reluctant role of the gatekeeper for society’s most important news and information.
While people may be divided on whether this is good or bad, there is another major change stemming from technology that is more clean cut in having a positive effect on consumers. The internet has allowed the news and content we consume to migrate away from centralized and capital-intensive sources (radio shows, cable TV), opening up many new and digestible formats of storytelling that were never before imaginable.
The barrier of entry for content has dropped towards zero, and it allows for many different “laboratories” to test new ideas, formats, and concepts until the winners are found.
New Formats to Experience
We are obviously advocates of the growing role of the visual medium for storytelling, which we aim to do mainly through infographics and data visualizations. While people have used visual storytelling since the cave drawing days, technology has really allowed this medium to hit a new stride as a way to break through the clutter. Further, science says that people crave visual content, and infographics provide a shareable, intuitive, distilled, and thought-provoking approach to sharing data.
Like infographics, the podcasting format – which is the subject of today’s post from Concordia University – has also recently began hitting a sweet spot for audiences around the world. This convenient audio format has been made possible through technology, and doesn’t rely on the same entrenched distribution channels as old school formats, such as radio.
As a result, podcasters can experiment more with the structures of their craft, while avoiding traditional forms of censorship. Today’s podcasts are breaking new ground daily with unique content that falls anywhere on the spectrum, from improvisational comedy to fact-dense educational features.
The Podcasting Boom
The podcast, a name originating from a portmanteau of “iPod” and “broadcast”, was first coined in 2004 by journalist Ben Hammersley of the BBC and The Guardian.
Despite being a feasible form of content even during the age of MP3 players and early broadband connections, the format has only really hit the mainstream in recent years. It’s hard to explain why, but most experts point to increased mobility, better production value, and a group of content creators that have recently managed to capture the imagination of the broader public.
Regardless, in recent years, the podcasting space has boomed to new levels of popularity. Today, the percentage of Americans that listen to podcasts is 24%, which is double what it was in 2013.
Further, the advertising market for podcasts is growing as well. In 2015, the ad market for podcasts was $69 million – but by 2017, the market was triple the size at an estimated $220 million. Podcasts allow advertisers to tap into very specific audience psychographics, and podcasts offer higher CPMs ($25-45) for successful publishers than traditional online content ($1-$20).
When and Where?
Aside from allowing new types of content to blossom outside of traditional distribution channels, podcasting has one other defining characteristic: mobility.
Just as streaming does for video, podcasts allow audio to be played in many situations where it was previously less feasible for a user to curate content. In fact, people listen to podcasts the most while driving (52%), traveling (46%), walking, running, or biking (40%), commuting on public transportation (37%), and while working out (32%).
This carves a pretty interesting niche that video and other content types can’t fill. And if podcasting content keeps getting better, people may even opt to listen in at other times outside of travel, building out the medium to even bigger heights.
The Topography of Mars: Visualizing an Alien Landscape
What is the surface of the Red Planet like? This beautiful map helps to break down the topography of Mars in awesome detail.
The Topography of Mars: Visualizing an Alien Landscape
The surface of the Red Planet is full of surprises.
While the Grand Canyon and Mount Everest are both impressive features on Earth, they are nothing next to Valles Marineris and Olympus Mons, their epic Martian counterparts.
Even more extraordinary, the overall difference between the highest and lowest point on Mars is 19 miles (31 km), whereas just 12 miles (20 km) separates the summit of Mount Everest from the bottom of the Mariana Trench on Earth.
This week’s map comes to us from Reddit user /hellofromthemoon, who carefully laid out the terrain of Mars in awesome detail.
Take a look…
Lay of the Land
Mars can be divided into two major regions, separated by a ridge of mountains roughly around the planet’s middle.
On the north side are lowlands that have been shaped by lava flows, creating a surface dominated by large plains. Meanwhile, the southern hemisphere is mountainous, with many meteorite impact craters, some of which stretch for hundreds of kilometers.
The Plains Game
The plains of Mars fall into two categories: the planitia (Latin for “plains”) and the maria (Latin for “seas”). The latter type is named after the sea because these regions appeared to be under water in the eyes of early astronomers. But actually, the surfaces of these regions are covered with many rocks, making them look darker to the eye.
The second type of plains are the planitia, and they account for vast areas covered by sand rich in iron oxide. The strong winds that blow the sand and dust around can change the configuration of the plains, forming new patterns on the surface of Mars. However, the planet’s features remain relatively unchanged over time.
One of the largest plains is the Utopia Planitia (Latin for “Nowhere Land Plain”) impact basin. This giant impact crater lies within a larger lava plain. With an estimated diameter of 3,300 km, Utopia Planitia is the largest recognized impact basin in the solar system.
As Above, so Below
The northern and southern hemispheres are vastly different from one another on Mars, and such a stark difference is unlike any other planet in the solar system. Patterns of internal magma flow could have caused the variation, but some scientists think it is the result of Mars taking one or several major impacts.
About 4.5 billion years ago, Mars formed from the collection of rocks that circle the sun before they formed the planets. Over time, the red planet’s molten masses differentiated into a core, a mantle, and an outer crust.
Understanding how the red planet’s topography changes over time is a crucial step in grasping how the planet formed. That is why NASA launched the InSight Mars lander on May 5, 2019. This probe will listen for vibrations deep within the Martian crust to further understand the composition of the planet.
Understanding the topography of Mars is critical for any mission to the planet, including the selection of a site for a potential colony. There are three basic criteria for picking a manned mission landing site:
- A spot that is sustainable in terms of water, energy generation, and building materials.
- A spot that is scientifically interesting for a long mission.
- A spot that is safe to land.
Brian Hynek, a planetary scientist and Director of the Center for Astrobiology at the University of Colorado at Boulder, offers five potential landing sites:
- Outer edge of Mars’ North polar ice cap
- Deep canyon of Valles Marineris
- Martian “glaciers” in the Hellas Basin near Mars’ mid-latitudes
- Arabia Terra
- Martian lava tubes and caves
With growing information from every new mission to Mars, a greater picture will help guide future human activity and ambitions on the planet.
The History of the World, in One Video
This epic attempt to condense the history of the world — including the rise and fall of empires — fits into a single video.
Throughout the history of the world, many civilizations have risen and fallen.
You may be familiar with the achievements of prominent societies like the Romans, Mongols, or Babylonians, but how do all of their stories intertwine over time and geography?
Visualizing the History of the World
Today’s video comes to us from Ollie Bye, and it attempts to integrate the histories of all major civilizations known by historians into a single, epic video.
Similar to the Histomap, it’s pretty much impossible for a video like this to be perfect due to biases and a general lack of data. However, it’s still a compelling attempt at showing global history in a short and sweet fashion.
Let’s look at some specific moments on the video that particularly stand out.
750 AD: The Umayyad Caliphate
One of the largest empires in history, the Umayyad Caliphate peaked sometime around 750 AD.
Conquering most of North Africa, the Middle East, and even parts of Europe (including modern-day Spain, Portugal, and France), the Umayyads commanded a formidable territory with an area of 11,100,000 km² (4,300,000 sq. mi) and encompassing 33 million people.
1279: Mongol Dominance
No history of the world is complete without a mention of the Mongols.
Nearby societies have always been on edge when nomadic tribes in the Eurasian Steppe entered into organized confederations. Similar to the Huns or various Turk federations, the Mongols were known for their proficiency with horses, bows, and tactics like the feigned retreat.
Under the leadership of Temüjin — also known as Genghis Khan — the Mongols conquered one of the largest empires by land.
The empire reached its greatest extent just two years after the death of Genghis Khan.
Later on, it fragmented into smaller empires that were also quite notable in the context of world history. For example, Kublai Khan — the grandson of Genghis Khan — even went on to begin the influential Yuan Dynasty in China.
1346: The Black Death
The video also shows other vital stats, such as an estimate of global population through the ages.
In the mid-14th century, you can see this number take a rare U-turn, as millions of people die from the infamous and deadly Bubonic Plague.
The Black Death — one of the most devastating pandemics in the history of the world — hit Europe in 1346, and it eventually killed 30-60% of the continent’s population. There is no exact figure on the final death toll, but historians estimate it to be somewhere between 75 and 200 million people throughout Eurasia.
1418: The Age of Discovery
The video also provides a 10,000-foot view of the Age of Discovery, a period of time in which European powers explored the world’s oceans.
This colonial period marks the beginning of globalization, creating wide-ranging impacts that set the stage for more modern history.
In the video, it’s possible to see European colonies develop in all parts of the world, as well as how they eventually morphed into the countries that dot the globe today.
Playing the History Game
While it is certainly ambitious, not everyone will agree that this is a successful attempt at portraying world history – even in the limited scope of time allotted.
One key detail that seems to be missing, for example, is showing the development of the indigenous societies that existed in North America for thousands of years. That said, it’s also not clear what data and records are available to show these maps over many centuries of time.
Despite the possible flaws, the video does pack a lot of information into a short period of time, creating a compelling opportunity for learning and discussion. Like the Histomap, it may not be a definitive history of the world – but instead, it’s a useful attempt that stimulates our appetite for more information about the world and the societies that inhabit it.
