Digital video brought $1.3 billion in revenue during the first six months of 2013, an uptick of 24 percent over the first half of 2012 at $1.1 billion. This according to recent report by the The Interactive Advertising Bureau (IAB).

Some additional highlights

• Internet ad revenues grew to a unprecedented $20.1 billion in the first half of 2013. That’s an 18 percent increase over 2012’s first-half ad revenues of $17 billion.
• Mobile revenues soared to $3 billion in the first half of 2013, representing triple-digit growth at 145 percent, from $1.2 billion in the same period in 2012.
• Search revenues in the first half of 2013 totaled $8.7 billion, up 7 percent from $8.1 billion in the first half of 2012.
• Display-related advertising revenues (the category that includes online-video ad spending) in the first half of 2013 totaled $6.1 billion, accounting for 30 percent of revenues in the time period. That’s up 9 percent from $5.6 billion in the first half of 2012 — but as mentioned the video portion of this is up 24 percent.
• The top three advertising verticals accounted for 46 percent of advertising revenue, including Retail at 20 percent, Financial Services at 14 percent and Automotive at 12 percent

In an eMarketer report earlier this year, the forecast growth for all of 2013 was expected to be 14%, reaching $118.4 billion.

Here’s a chart I made based on IAB’s reported first-half of the year data just to give you a general sense of growth over time. Sorry it’s backwards. My excel skills are rusty.
