T-Series Is Number One On Youtube

PewDiePie and T-Series are the two of the most-subscribed-to YouTube channels.
They have been engaged in a months-long battle to secure the title of most popular YouTuber.
T-Series is an Indian music label.
Business Insider reports it's become the first YouTube channel to reach 100 million subscribers.
The achievement comes after PewDiePie pleaded with his fans to stop campaigning for him.
His "Subscribe to PewDiePie" meme was referenced during the Christchurch, New Zealand, shootings.
