Google had almost 40% of the US online advertising market in the first half of 2007, up from 34.6% for the corresponding period in 2006.

Its ad income was $3.98bn (€2.8bn), a vast increase on the $2.7bn in 2006. However, the overall ad market increased by about $2bn.

Is there no stopping this company? This news might make up for opposition to its takeover of DoubleClick.
