C2C
) and where they initiate trading with companies (
C2B
). These 
monikers are less widely used (e.g. 
Economist
, 2000), but they do highlight significant differences 
between Internet- based commerce and earlier forms of commerce. Consumer-to-consumer 
interactions (also known as peer-to-peer or person-to-person, P2P) were relatively rare, but are 
now very common in the form of social networks. Hoffman and Novak (1996) suggested that 
C2C interactions are a key characteristic of the Internet that is important for companies to take 
into account, but it is only in recent years with the growth of always-on broadband connections 
and mobile access to the web that these have become so popular. P2P transactions are also the 
main basis for some online business models for digital businesses such as Betfair (see Mini case 
study 1.4) and eBay (
www.ebay.com
, see Case study 1.2) which are still run on a business basis, 
and some blogs which are not run by companies but by individuals.
Finally, the diagram also includes government and public services organisations which 
deliver online or e-government services. As well as the models shown in Figure 1.11, it has 
also been suggested that employees should be considered as a separate type of consumer 
through the use of intranets; this is referred to as employee-to-employee or E2E.
