Online Video Ad Views, December 2011 – January 2013 [CHART]

Online video ad views fell from a peak of 11.3 billion in December 2012 to just 9.1 billion last month, a 19.5% decline, according to the latest figures from comScore. That mirrors a 22% drop between December 2011 and January 2012, suggesting that there is a seasonal trend at play. While video ad views were down significantly in January of this year, they still were up 62.5% year-over-year, underscoring just how rapidly the online video advertising market is growing.

Particularly in longer-form content, ad completion rates continue to be strong – and increasing – per the latest data from FreeWheel.

Last month, video ads accounted for 20.1% of all videos viewed, and 1.7% of time spent viewing video online. That compares with 12.2% and 0.9%, respectively, in January 2012. Read the rest at MarketingCharts.
