The Rise of On-Demand Audio

Broadcast first emerged in the early 2000s as a way for people to subscribe to favorite radio shows or listen to audio content on their own schedule. By making audio available on-demand through RSS feeds, broadcast allowed listeners to tune in whenever and wherever they wanted rather than having to listen live. Early podcasts included personal blogs, talk radio shows, and serialized stories. This on-demand functionality was highly appealing to listeners and helped drive early adoption of the format.

Growth of Independent Creators

As portable mp3 players like the iPod grew in popularity in the mid-2000s, the number of podcasts and listeners began increasing more rapidly. Many new podcasts were started by independent creators looking to build an audience outside of traditional media. Broadcast gave a voice to those interested in niche topics that may not attract a large radio audience. It allowed personal passions and interests to be shared on a global scale. Individuals launched podcasts on every possible subject, from true crime to sports to comedy to philosophy and more. Over 100,000 podcasts existed by 2010, covering nearly any conceivable interest area.

Smartphones Fuel Explosive Growth

The arrival of smartphones in the late 2000s was truly a game changer for Podcasting. With phones that could easily download and store podcast episodes, listening became even more portable and convenient. Developers also created dedicated podcast apps like Overcast and Podcast Addict that optimized the listening experience. As smartphone ownership skyrocketed over the next several years, so too did podcast listening figures. By 2015, the number of monthly podcast listeners in the U.S. alone had reached over 50 million. Podcasts found audiences globally as listening expanded internationally on mobile devices. Smartphones allowed podcasts to scale far beyond what was possible through MP3 players alone.

Celebrities and Major Networks Take Note

As average podcast download numbers soared into the millions per month for top shows, major media networks took notice of broadcast's potential reach and revenue opportunities. Established radio personalities like Adam Carolla launched their own popular podcasts that found listeners eager for fresh content. Celebrities like Chelsea Handler entered the podcast scene with talk shows built upon their fame. Entertainment giants like NPR, BBC, and ESPN launched ambitious podcast divisions to capitalize on audio's resurgence. Advertisers followed listeners to podcasts and offered lucrative sponsorship deals to popular shows. Broadcast had gone mainstream and was becoming a serious business as prominent names flocked to the format.

Personalities Drive Enduring Favorites

While there are countless Podcasting covering a huge variety of topics, some common attributes seem to make for an enduring favorite listen. Having an unusually charismatic, authentic and enthusiastic host is a key factor in building a devoted fanbase. Shows hosted by friends just chatting like My Favorite Murder or Armchair Expert attract millions of regular listeners drawn in by the hosts' lively personalities as much as any topic. Niche genre shows find cult followings when presided over by experts with infectious passion, such as Lore for folklore or The Allusionist for linguistics. And hilarious comedians like Joe Rogan or the Your Mom's House crew have powered their podcasts into pop culture phenomenons through force of comedic personality alone. Certainly, compelling content matters - but an unpredictable yet friendly human voice seems integral to any podcast's long term success.

Becoming a Broadcast Powerhouse

It's been remarkable to witness the Podcasting industry develop in under twenty years from a novelty to one generating billions in annual revenue. According to the IAB, podcast ad revenues grew 84% in 2019 alone to surpass $1 billion that year. Broadcast's future looks bright as it continues branching out. Beyond audio, many top shows film companion video content or host live events. Podcast platforms are developing new listening experiences using artifical intelligence through features like personalized recommendations. And podcasts may start to experiment with emerging tech like augmented reality and virtual reality in creative new ways. With so many dedicated podcast creators and fans around the world, it's hard to envision anything slowing the medium's momentum. Broadcast has firmly established itself as a global powerhouse in digital media and entertainment.
