After a months-long feud that included rap songs, printer hacks, and a number of publicity stunts by both PewDiePie and his dedicated fans, PewDiePie's channel was finally defeated by T-Series. However, T-Series' victory didn't last long, as PewDiePie's channel has once again overtaken it to regain its claim as the most-subscribed channel on YouTube.
At the time of this writing, PewDiePie has a little over 88,909,000 subscribers on YouTube, whereas T-Series has over 88,907,000. The gap keeps growing wider as PewDiePie's channel gains more subscribers and puts more distance between itself and T-Series. PewDiePie's channel gained thousands of subscribers in a matter of minutes after it was overtaken by T-Series, and the number keeps going up.
It seems T-Series surpassing PewDiePie's subscribers has inspired his fanbase to rally behind him and keep his channel as the most-subscribed on YouTube. This is even without PewDiePie doing any special events, like the various video game livestreams he has done in the past to keep his channel ahead of T-Series.
In the past, we've seen PewDiePie livestream Minecraft, Fortnite, and even Roblox in his efforts to stay ahead of T-Series. He's also received some help from his fans, who have gone as far as to purchase expensive advertisements in Times Square to promote PewDiePie's channel.
PewDiePie's fans have also gotten the YouTuber in some hot water recently, as some have gone too far to promote the ongoing feud between PewDiePie and T-Series. There was one recent incident where people vandalized a World War 2 memorial with "subscribe to PewDiePie," and as previously mentioned, someone else actually hacked printers to print similar messages. It's worth pointing out that PewDiePie didn't instruct his fans to do these things, and has asked them not to do anything "illegal" when supporting him in his battle against T-Series.
PewDiePie has also received help from other YouTubers and celebrities to help him stay ahead of T-Series. Perhaps the biggest example of this is billionaire Elon Musk hosting PewDiePie's popular Meme Review series in a special episode that has amassed over 20 million views on YouTube.
Moving forward, fans can expect PewDiePie to continue coming up with clever ways to stay ahead of T-Series. T-Series also seems to be ramping up its efforts as well, though, and so it will be interesting to see which channel is on top when it's all said and done.
