The magazine is repositioning itself as a practical guide to making the PC an integral part of home entertainment.
This means that, for the first time, the 64,000-circulation magazine is actively targeting PROs who have clients with cutting edge, high-end products such as plasma TVs, digital videos and other home technology equipment.
The introduction of two new sections, PCF Hub and PCF Hardcore, will add 16 pages to the title over its next two issues.
Group publisher Dave Taylor said: 'This is about the PC as a hub of your media usage within the home. It is aimed at people who have broadband in their home as a starting point, and who use their PC, for example, as an internet music server or TV or video recorder. We are looking at all the cutting edge products. These are the sorts of things that PROs tend to get more excited about because they are the most interesting.'
The shift in the magazine's focus is reflecting changes in the PC market, Taylor said.
'The idea of PCs as an end user product has passed. During the 1990s, up to the internet boom, there was a great growth in consumer sales. Since then there has been a move back to what we would call hardcore users.
It is now about what people use their PC for, such as digital cameras or digital video. It has become a piece in the jigsaw,' he said.
Each new section will have a slightly different focus. PCF Hub will cover digital entertainment, while PCF Hardcore will offer hints on editing and expanding games on the PC.
The changes to PC Format come as Future is relaunching two other titles this week. Future Music is to add 48 pages, which will comprise of three new sections, including greater coverage of music software.
Computer Music is set to place greater emphasis on the practical elements of making music on Mac or PC.
