The doubters were lining up before Cobra Kai’s debut episode even aired in May 2018. A 1984 karate movie sequel series, starring two actors whose biggest credits were both decades old, was created for a streaming service that most people hardly used. Just the idea sounded like a sentimental gamble that would flare up for a week and then subtly fade away. It is important to focus on what actually transpired.
The first episode of the show received over 50 million views when it debuted on YouTube Red, a subscription service that was having trouble differentiating itself from Netflix and Amazon. Almost everyone was taken aback by that figure, including, apparently, YouTube. Eventually, the platform completely abandoned scripted originals, and Netflix was ready when it let Cobra Kai go. Completed in 2020, that acquisition proved to be one of the streamer’s more subtly significant decisions that year.
Cobra Kai became the most popular series on Netflix in the US a few days after it debuted in September 2020. not only in recent releases. In the middle of everything. In its first 28 days, it was viewed by 50 million accounts, surpassing Ryan Murphy’s Ratched, which at the same time had created a lot of buzz. By early 2021, 73 million people had watched, according to The Guardian. No one had anticipated these show numbers.
The viewing numbers by themselves don’t explain why that occurred, so it’s worth taking a moment to consider why. Numerous highly promoted programs have achieved those figures before disappearing from view after just one season. Cobra Kai ended in February 2025 after six seasons and sixty-five episodes, setting a Guinness World Record in the process. Instead of simply tuning in, the audience returned. repeatedly.
The writing was part of what kept them. Rather than being executives searching for a well-known property to strip-mine, the show’s creators, Josh Heald, Jon Hurwitz, and Hayden Schlossberg, were obviously fans of the original movies. Without confusing new viewers, the Easter eggs were deep enough to reward devoted viewers.
Characters from Karate Kid II that hadn’t been seen in decades made a purposeful comeback. Instead of being replaced, the franchise mythology was enlarged. As you watch the show, you get the impression that the writers were protective of the content in a way that isn’t always the case when studios bring back old properties.
The character development was also beneficial. The antagonist of the first movie, Johnny Lawrence, was given a second chance at life as a man who sincerely wants to get better but fails in very human ways. William Zabka was nominated for an Emmy for Outstanding Comedy Series in Season 3 as a result of his performance receiving significant critical acclaim. People didn’t just put up with the show; they genuinely cared about it, as evidenced by its 94% critic and 96% audience ratings on Rotten Tomatoes.
The timing is also worth mentioning. In 2020, as the streaming wars heated up, Netflix’s ability to take an underleveraged property and put it in front of a large audience was starting to look familiar. In a way that YouTube was never able to create, Cobra Kai profited from that platform effect. However, the Netflix bump is only effective if the underlying product is worthwhile to watch. The move elevated the profiles of you, Lucifer, and Cobra Kai; in terms of cultural presence, Cobra Kai outlasted them all.
A success or a failure? What transpired is almost understated in the question. Cobra Kai started out as a project that many thought was a vanity exercise, ran on a platform that couldn’t support it, was picked up by the biggest streamer in the world, and went on to become one of the more genuinely adored TV shows of the early 2020s.
The figures were substantial. There was greater audience loyalty. After six seasons, the show ended on its own terms, accomplishing something that reboots seldom do: it made viewers care about characters they assumed they already knew everything about.
