E-learning has evolved since computers were first used in education. There is a trend to move toward blended learning services, where computer-based activities are integrated with practical or classroom-based situations. 

Computer Based Learning (CBL) refers to the use of computers as a key component of the educational environment. While this can refer to the use of computers in a classroom, the term more broadly refers to a more structured environment in which computers are used for teaching purposes. The concept is generally seen as being distinct from the use of computers in ways where learning is at least a peripheral element of the experience (e.g. computer games and web browsing).

CBL has entered mainstream corporations for frontline delivery for things like new hire orientation, workplace specific training, expanding company policy & procedures, as well as government regulated training like WHMIS, CPR, First Aid, Fall Protection. Confined Spaces, Asbestos Awareness, PPE, Fire Extinguisher training. All of these programs are being delivered efficiently and effectively using CBL.

The worldwide e-learning industry is estimated to be worth over 51 billion dollars according to conservative estimates.  Developments in high-speed Internet and multimedia technologies are the basic enabler of e-learning, with content, technologies and services being identified as the three key sectors of the e-learning industry
