Digital video will overtake television by the end of the decade according to YouTube's chief business officer Robert Kyncl speaking at the Consumer Electronics Show (CES).
While Kyncl pointed to mobile viewing and virtual reality as drivers of the shift to digital, he also said his prediction is based on lower TV audiences.
He cited a Nielsen study that came out last month that said TV viewing peaked in the 2009-2010 season and has been declining ever since.
According to YouTube, the number of hours people spend watching its videos has increased by 60 per cent year-over-year, the fastest growth it has seen in two years.
The number of hours people spend watching YouTube videos on mobile has risen 100 per cent year-over-year.
