I just got back from Dubai after attending a training course on Mediadisk. This is the world's leading media database, and includes around 800,000 contacts from 200,000 media outlets. The main advantage for this database is appreciated by anyone working on media communications on a daily basis.
Building and filtering lists according to many different criteria, grouping the data, and distributing emails and press releases is much easier with this system. I also saw how much hard work it takes for the researchers to gather and constantly update the regional data, which is in itself a feature of the product.
Mediadisk has a Middle East & North Africa module available, and anyone interested can book a free demo, to get to know the system. More details are available on the Products page of Mediadisk.
