Top Finland-based mobile phone company Nokia has acquired Enpocket, a U.S. cellphone screen advertising firm, according to Reuters. The world’s leading handset maker pushes into a market which is expected to swell in the coming years. Mobile companies are slowly making moves into the potentially lucrative market, aided by new technologies and the widespread availability of more advanced phones.

In fact, when the Nokia made their plans public last month, the company’s shares rose by 0.8 percent. Nokia did not disclose financial details of the deal which is expected to close in the fourth quarter.

The Boston-based Enpocket offers the Enpocket Platform, is described as a “carrier-grade mobile campaign management and delivery system” designed for operators, advertisers and publishers. It has customers in Europe, Asia and the U.S., including Vodafone, Pepsi, Telefonica, AT&T, British Telecom and Sprint.

It is a very interesting move, according to analysts. It gives a clear picture of the speed in which Nokia’s new organization is expanding into software and services,” said Jari Honko of eQ in the Reuters article.

Another analyst, Eden Zoller of Ovum, also stated that Nokia does well in acquiring Enpocket, because the company is a strong mobile advertising specialist whose technology platform has a solid analytics component. Enpocket gives Nokia a leg up in mobile advertising and credibility that it needs to be taken seriously in the space.

Nokia also unveiled its new Ovi service, which will combine a new digital music store and a gaming service with its navigation offering.

“Effective interactive advertising on the mobile device can create tremendous value for the mobile industry while bringing new Internet services to people around the world,” Enpocket President Mike Baker said in a statement.
