Google-owned DoubleClick buys ad tech startup

SAN FRANCISCO — DoubleClick Inc., an Internet ad service owned by Google Inc., said Thursday that it bought online ad technology startup Invite Media.

Invite Media, which is based in New York and Philadelphia, makes tools to help marketers bid on online advertising space.

Financial terms of the acquisition were not disclosed.

Google bought DoubleClick in March 2008 for $3.2 billion. More recently, the online search leader passed the final regulatory hurdle in its $750 million acquisition of mobile ad service AdMob in May when the Federal Trade Commission unanimously approved that purchase.

Google shares rose $1.83 to $507.43 in after-hours trading, having finished regular trading up $12.23 at $505.60.
