The growth of US streaming services like Netflix and Hulu is outpacing traditional cable by a wide margin, according to research by The Convergence Consulting Group.

The US revenue for video streaming services like Netflix and Hulu grew by 29% to $5.1 billion in 2015. And while the US streaming industry in 2015 was a fraction of its cable, satellite, and telco TV counterpart (with revenues of $105 billion), that sector grew by just 3% in 2015.

2015 saw an explosion of new players in the industry, from NBC’s all-comedy Seeso to Sony’s PlayStation Vue, but Netflix and Hulu still make up 98% of the revenue for non-cable (“over-the-top”) streaming video services — excluding Amazon. Convergence estimates this market share will decline to 91% in 2016.

And streaming isn’t slowing down. Convergence predicts it will grow to $6.7 billion in 2016.

Convergence also saw a growth in “cord-cutters” and “cord-nevers,” households who don’t hold a traditional TV subscription and instead rely on things like streaming services for video. Analysts found 20.4% of households fell into this category at the end of 2015, up from 18.8% at the end of 2014. By the close of this year, Convergence predicts this will grow to 21.9%.
