Nokia has announced the completion of its acquisition of mobile advertising technology and services firm Enpocket.

The mobile giant said that the move forms a key plank in its attempts to develop the world's largest mobile advertising marketplace.

Enpocket's offerings are designed to allow companies to plan, create, execute, measure and optimise mobile advertising campaigns.

"With the close of this transaction, we will create an exciting business focusing on advertising," said Tero Ojanperä, chief technology officer at Nokia.

"We will offer a strong suite of services and solutions to enable brands, publishers, telecoms operators and others to run targeted advertising and marketing campaigns for mobile audiences."
