In 2010, Deloitte predicts that over 90% of television watched and over 80% of audio content consumed will still be via traditional linear broadcasts according to programming schedules, despite the proliferation of on-demand options. Linear viewing is expected to remain dominant due to its ease of use and inertia, as choosing content individually is tedious for most viewers. Factors like new TV purchases, HD adoption, and failures of online video sites could further increase linear viewing in 2010.
