Search remains the main engine for Google’s core business, but display is rising fast: we estimate display gross revenue will reach $9.2 billion in 2013, representing 16% of projected gross revenue (excluding Motorola)
Gross revenue from YouTube looks set to more than double to nearly $4 billion by 2013. Revenues from Google’s ad networks and platforms are also growing strongly, mainly to the benefit of publishers
We project Google’s net revenue from display next year will amount to $4.2 billion, equal to 10% of net revenue from its total advertising business
