Streams Mexico service acquires more than 10,000 subscribers

Mobile Streams plc, the AIM quoted mobile content and data intelligence company, is delighted to announce that it's LiveScores service in Mexico has now acquired more than 10,000 subscribers. The service, which only launched at the start of August, has passed this milestone in just two and a half months, six months earlier than the Company had internally anticipated.

The fast pace of growth along with constantly exceeding subscriber targets indicates that the Company is likely to exceed its initial published forecast of the service delivering at least $1.5 million in revenue over 3 years which was based on approximately 3,000 subscribers in October rising to 95,000 over 3 years. The Company will update its forecasts based on the greater than expected number of subscribers in due course.

The Company can confirm it is in advanced discussions regarding launching this service in several additional markets. A further announcement on the next launch will be made imminently.

Nigel Burton, Non-Executive Director, said:

"Acquiring over 10,000 subscribers so quickly in Mexico is a great achievement for the whole team and I am delighted with our progress to date. As we expand into new markets and revive old ones, I very much look forward to seeing this growth continue into the future."
