Electronic commerce revolutionises both global economies and marketplace. A number of developed countries have demonstrated clear leadership in eCommerce, as demonstrated by the level of ICT penetration in organisations and households. However, traditional economies have experienced a much slower uptake of eCommerce. This is attributed to difficulties in enhancing the usage of personal computers and in increasing the utilisation of the Internet and Information Communications Technologies (ICTs) throughout their production mechanisms. This paper concentrates on Greece and demonstrates a number of indicators that synthesise the level of eCommerce penetration. The Greek economy is going through a major transformation and ICTs may be instrumental in its international competitiveness. The paper provides a comprehensive overview from both the production/supply (macro and micro) and consumption/demand sides. It focuses on the level of ICT penetration in Small and Medium-Sized Enterprises and concludes that eCommerce in Greece is still in its infancy. The paper provides essential background information for enterprises and policy makers interested in eCommerce in Greece and the competitiveness of the country in general.
