This paper takes a new look at Porter’s five competitive forces model. In doing so, this work
proposes a new competitive forces model centered on the travel and tourism industry that
includes two additional forces, namely information technologies and government regulations,
and adds an additional element to the buyers’ perspective, namely the power of intermediaries.
This model is applied in the case of Greece and, although several limitations, from the
findings it is proven as capable of explaining the competitive forces that affect the level of
competition in the Greek travel and tourism industry
