MicroScope

MicroScope is a magazine for computer manufacturers, distributors and resellers within the ICT channel which was founded in 1982.

In March 2011 owners Reed Business Information sold MicroScope and its sister title ComputerWeekly to TechTarget and the print edition ceased publication.

At the last BPA Worldwide audit in 2008, the circulation figure stood at 22,275 (BPA June 2008).

Following the closure of the print edition, MicroScope is now available only online and in a monthly digital format.

Topics covered within the magazine include news and analysis and assessments of issues within the marketplace. The classic audience for the magazine work within the 'two-tier' channel either in distribution or at a reseller. The readership includes volume distributors, value-added distributors, resellers, VARs, ISVs and technology consultants.

Over the past 28 years the channel has matured and continues to go through a process of consolidation. During the time the magazine has been publishing computers have become mainstream and the concept of the microcomputer is now fundamentally accepted in both workplace and home.
