7. Admeld: $400 million
The advertising optimization platform for publishers was acquired by Google in 2011.
The advertisement optimization company based in the state of New York was another expensive Google’s acquisition.
They needed the company to optimize their own ads and yea, gain more money. Admeld had been already famous for working with major companies such as Weather Chanel and Fox News.
It seems like another good acquisition, considering the fact that Google is looking to combine Admeld with another major company.
Admeld was acquired by Google for $400 million, making it one of the most expensive Google acquisitions in the world.
