Tubi says it's continuing to gain momentum, drawing more viewers to its free-streaming service and driving up more overall viewing time.
In December 2019, its monthly active user base grew to 25 million from 20 million six months earlier while total viewing time hit more than 163 million hours watched, a 160 per cent year-on-year increase, the company said.
That suggests Tubi users on average watched 6.5 hours of video on the service for the month.
The San Francisco-based company said its content spending will "exceed nine figures in 2020," or more than $US100 million ($A149 million) to expand on its current library of some 20,000 movies and TV series.
Last year Tubi pegged content spending at about $US100 million.
Tubi's 250-plus content partners include Warner Bros, Paramount and Lionsgate.
Currently available in the US, Canada and Australia, Tubi plans to launch in additional territories including Mexico and the UK in the next few months
Tubi faces a growing array of competitors in the ad-supported VOD space, including ViacomCBS's Pluto TV, Amazon's IMDb TV, and Walmart's Vudu.
"Our growth over the last year is a clear testament to the success of our focused strategy in a now-cluttered marketplace," Tubi CEO Farhad Massoudi said.
"We're excited people globally have embraced Tubi as a complement to subscription video and aim to deliver an even larger library of premium content in 2020."
