To this end MMS has similarities with Internet email and standard IETF protocols. As with any new technology it is difficult to accurately predict the position within the next 5 years, although based on previous experience with WAP and SMS it would be fair to say that these protocols will increase in usage over the next 5 years and become legacy for a further 5 years following which, users will migrate onto the next wave of messaging. Significant revenue growth and data usage is expected to be driven by consumer usage of MMS.
