The purpose of this report is to study effects of SMS and MMS as channel additions on customers’ relationships with brands. Empirical studies are reported for three brands in which have added SMS and MMS as brand channel additions (FINN, TV2 and Big Brother). The main results of these studies may be summarized as follows. * SMS seems to have a more positive effect than MMS both on the variables included in the extended Relationship Investment model (Rusbult, 1980) and on main channel use. * The effects of SMS/MMS as channel additions are more positive on direct relationship investments and indirect relationship investments than on the remaining variables in the extended Rusbult model. The effects of SMS/MMS on main channel use seem to be mediated mainly by direct relationship investments made by the consumer.
