PewDiePie vs T-Series: YouTube star concedes battle to be site's biggest channel with song 'Congratulations'

PewDiePie has conceded his hard-fought battle with T-Series with a music video of his own. The YouTube star whose real name is Felix Kjellberg has finally stopped being the site's biggest channel – a slot he held for years – after a challenge from T-Series, which hosts Indian music videos and has grown quickly. Over recent months, the two channels have fought to get control of the top spot, with PewDiePie's fans using a whole host of publicity techniques in an attempt to keep him as its most popular channel. We'll tell you what's true. You can form your own view. But T-Series kept outpacing its growth and has now settled as YouTube's biggest channel.
