The Czech tie-up will enable the group to develop its networks in growth markets and sectors, and strengthen its capabilities in digital media. The terms of the deal remain undisclosed.

To December 2007, Adventures turned over €1.5 million (£1.1 million), reporting gross assets of €1 million (£800,000). It provides online services to high profile clients, such as the Czech Ministry of Foreign Affairs, Nokia and SUN Microsystems.
