Over the past few weeks and months, two titans of the vlogging game have been battling it out to see who is the top dog.
And in an exciting turn of events, Felix Arvid Ulf Kjellberg has made a strong case to take the crown as his channel now has more subscribers than the entire population of Germany, which is 82,887,000 people.
Last year the controversial 29-year-old saw his popularity skyrocket with a 700 per cent surge in monthly subscribers in October.
This was after he launched a campaign to boost his following in a bid to fight off competition from T-Series, an Indian company that primarily shares Bollywood music videos.
And it's a good thing he did, because according to analysis from Tubular, PewDiePie would have been knocked off his perch by 29 October if he hadn't - something which the social media star was obviously never going to let happen.
PewDiePie begged viewers to 'smash subscribe', and they didn't disappoint with some of his devoted fans even going out and sticking up posters in cities across the world encouraging people to follow his channel. If only they had that much get up and go about things that really mattered. Sadly not.
But it wasn't regular fans that pushed him over the threshold last year, it was the support of two other big name YouTubers.
Logan Paul and Mr Beast threw their substantial weight behind the campaign. The former said he would donate to charity if people subscribed, while the latter paid for radio ads and billboards promoting PewDiePie, according to Business Insider.
The fellow vlogger even did a 12-hour live stream in which he said 'PewDiePie' 100,000 times. The video has been watched more than nine million times.
Another fellow Youtuber, Davide Biale, better known as Davie504, stuck his colours to the mast when he flew to India to sing Pewd's diss track, B***h Lasagna, outside the headquarters of T-Series.
An utter waste of time but kind of impressive at the time time.
Business Insider calculated that PewDiePie gained 13 million subscribers between September and December - almost double the amount gained in the entirety of 2017. In December alone, 6.62 million people subscribed to his channel, representing a 700 percent acceleration in growth on September.
Consequently, he remains top dog in the YouTube world and it doesn't look like he plans on moving out of the way for anyone.
But with rival T-Series boasting more 82,741,000 subscribers, the war rages on.
