Korean Online Video Advertising Market Size

Hold on tight, because we’re about to take a thrilling journey through the ups and downs of COVID-19 and its impact on the world of online video advertising in South Korea.

Let’s go back to July 2020 when the number of COVID-19 cases was relatively low and the general belief was that it was “under control.” Ah, those were the days. But little did we know, things were about to take a wild turn. In March, the outbreak reached its peak with a staggering 851 cases in a single day. That’s right, the battle had begun.

But fear not, because South Korea kicked into high gear with aggressive tracing mechanisms. They were on a mission. Throughout the summer, the number of cases hovered around 50 per day. It seemed like smooth sailing, until… the “second wave” hit in mid-August. And it didn’t stop there. This wave continued with a vengeance until the end of September.

Then came the fall season, a time of worry and uncertainty. The numbers were lower, but they kept fluctuating, keeping everyone on their toes. But hold on tight, because the most serious wave was yet to come. Winter arrived, and with it, the dreaded “third wave.” Daily cases shot up to a staggering 1,000 cases per day. It was a battle against an invisible enemy, my friend.

As restrictions tightened and people found themselves spending unprecedented amounts of time at home, the world of online video advertising felt the impact. Take a look at the graph below, and you’ll see the correlation between the number of cases and the money spent on online video ads.

Now, let’s break down the numbers. In the summer, spending on advertising was relatively lower compared to the following months. But once the first wave hit, something incredible happened. Online video ad spending surged from 94.1 billion KRW in August ’20 to a staggering 101.4 billion KRW in September ’20.

But hold onto your hats, because the winter season brought even more spending. Brands saw the golden opportunity to reach people who were spending endless hours on the internet. So, the spending on online video ads soared to new heights. By the end of 2020, the spending had reached a jaw-dropping 112.5 billion KRW, an 18 billion KRW increase from July 2020. Can you believe it?

So there you have it. The tale of how COVID-19 waves and the rise of online video ads collided in South Korea. It’s a story of resilience, adaptability, and seizing opportunities in the face of adversity.

The Top 10 Media for Online Video Ads

When it comes to social media, three powerhouses reign supreme: YouTube, Facebook, and Instagram. These platforms have captured the hearts and minds of the Korean population like never before. In fact, a mind-blowing KISDI report revealed that a whopping 52.4% of Koreans owned some form of social media in 2020. Can you believe it? That’s more than half the country hooked on social media!

Now, let’s talk about the COVID-19 outbreak. It was like pouring fuel on an already blazing fire. The usage of the internet and social media applications skyrocketed, as people sought connection, entertainment, and information during these challenging times. Social media became a lifeline.

According to data from the country’s 33.7 million Android smartphone users, YouTube emerged as the undisputed champion. In September, users spent 53.1 billion minutes on YouTube, compared to 44.3 billion minutes the previous year. That’s a 20% increase! It’s like the entire nation was glued to their screens, consuming captivating content on YouTube.

But wait, there’s more! Feast your eyes on the chart below. It reveals a comparison of spending on online video ads across major media platforms in South Korea during the months of November and December.

Well, they ramped up their existing campaigns, such as “elihigh,” an interactive education platform for children.

And it doesn’t stop there. Nexon, the Korean–Japanese video game publisher, also turned heads with a remarkable 166.6% increase in advertising spending. Why? The answer is simple: the usage of games went through the roof during the COVID-19 pandemic. As people sought entertainment and escape, the world of gaming provided solace and excitement. It’s a trend that captured the attention of advertisers and players alike.

The Future of Online Video Advertising in Korea

South Korea’s multi-billion dollar online advertising industry is one of the biggest in the world, and it has grown nearly every single year in the past two decades. Since 2015, online ads on mobile and dekstop have surpassed all other methods of advertising, like print and outdoor advertising.

Online video ads specifically, are becoming more and more important to brands looking to make a lasting impression on consumers. With more advances in technology, online video ads are more clever and popular than ever before. For example, users are 3 times more likely to watch YouTube ads vs. TV ads.

Both big and small companies in Korea were seen branching out and spending more for online video ads. When looking at the top 10 industries and the trends on online video ads, it was observed that half increased their spending, and the other half decreased their spending on advertisements. This is a prime example of how COVID-19 has affected industries in drastically different ways.
