Once e-learning was the solution to all our ills: development at your desk and in your own time.
But now we are told it's not good enough on its own - we need blended learning.
Roger Delves, programme director at Cranfield School of Management's Centre for Customised Executive Development, says: 'Any form of teaching that involves face-to-face tuition as well as the web would be defined as blended learning,' he says. 'It's not just a question of which media you are using.
'For example, many blended development schedules include web-based programmes, face-to-face tuition, coaching and experiential learning.'
Not that different from good old-fashioned classroom teaching, then? 'No,' says Mr Delves. 'But there is one key difference, and that's technology.'
A clash is developing between synchronous forms of communication, like chat rooms or video conferencing and asynchronous forms, like email.
'The whole selling point of e-learning was it gave people the freedom to do their work whenever it suited them. With chat rooms or virtual classrooms, everyone has to 'attend' at the same time.'
