Dive Brief:

• According to data compiled by eMarketer, tablets will soon overthrow PCs as the primary medium for viewing videos. 
• Time spent viewing video on tablets is predicted to grow by 54% in 2014 to approximately 20 minutes a day, compared to 22 minutes a day on PCs — a figure that is flat from last year. 
• Despite major growth in mobile video viewing — both on tablets and smartphones — ad dollars remain focused specifically on desktop. Spending for online video ads this year will top out at $4.45 billion, compared to a $1.44 billion spend on mobile video ads. 

Dive Insight: 

Advertising lag in embracing mobile certainly isn't unique to video ads. Advertisers and brands historically have been hesitant to move ad dollars until a medium has proven itself. As more reports like this are released, advertisers will hopefully see that the transition needs to be made.
