The magazine's group editor Paul Newman has been moved to a new role concentrating on new launches and work on developing sister title Practical Web Projects.
He has been replaced by deputy editor Thomas Watson. Other changes include the promotion of James Thornton to features editor.
Watson said the magazine will be reviewed over the year, with many options - including a redesign - being considered.
He added that the widespread use of broadband has meant that internet users are now looking at different issues, particularly when it comes to getting the best deal.
He said: 'My advice to those in PR contacting us is to make sure they are up on their broadband.'
