Video streamer Bilibili Inc announced on Thursday total revenue jumped 91 percent in the quarter ending Dec 31, fueled by robust growth across its mobile games, value-added services, advertising and e-commerce businesses.

Total net revenue for the quarter hit 3.84 billion yuan ($588.5 million), Bilibili said in its unaudited financial results. Gross profit expanded 137 percent to 944.1 million yuan, up from the same period in 2019.

Average monthly active users, a common indicator of customer loyalty, reached 202.0 million, up 55 percent year-on-year.

But such momentum has yet to stop the company from operating in the red, with fourth-quarter net losses more than doubling to 843.7 million yuan from 387.2 million yuan a year ago.

Bilibili captured the attention of a wider audience beyond its traditional Generation Z userbase when a 22-year-old content creator dubbed "Hetongxue" uploaded a video where he interviewed Apple CEO Tim Cook.
