The YouTube channels that gained the most subscribers in 2019 show the platform's current trends and the areas that are growing rapidly.
YouTube's top stars, like PewDiePie and MrBeast, continued to dominate, obtaining tens of millions of new subscribers in a single year.
But PewDiePie was dethroned this year in total subscriber count by Indian record label T-Series, which also topped the list of fastest-growing channels, gaining a massive 42 million new subscribers in 2019. The success of T-Series — and the six other Indian channels that cracked this list of 21 channels with the most subscriber growth — shows the rising importance of India for YouTube.
Multiple Russian-speaking kid YouTube stars also made this year's list, including Anastasia Radzinskaya, the face of "Like Nastya Vlog." The 5-year-old star, who was born in Russia and lives in Florida, earns an estimated $18 million yearly from her online success, according to Forbes. With the booming success of her YouTube channels, Radzinskaya's family plans to extend her YouTube empire by launching toys, mobile games, and even publish a book, Forbes reported.
Two of her Radzinskaya's channels made the list: "Like Nastya Vlog" (which gained 27 million) and "Stacy Toys" (which gained 13 million).
