The same limitations apply to mobile phones which, for all the promise and hype of UMTS, cannot provide even a fraction of a percent of the capacity terrestrial radio broadcasters need. Moreover, listening to radio on a mobile phone connection is never going to be free to air. In any analysis, terrestrial radio remains the most powerful and compelling consumer proposition. Digital radio adds considerable value to the proposition, yet keeps all the attributes of existing radio. IBOC will be made to work and may be successful if the consumer appreciates the marginal benefits.
Satellite is dependent on geography and subscription.
DRM may find favor in limited markets, starting perhaps with international broadcasters. The internet and mobile phones are extension platforms, not replacements. Meanwhile, Eureka has already gained considerable momentum and commitment which will ensure its continuance. One realistic option is to encourage a combination of technologies to satisfy market needs. In countries like Australia, DRM would be ideal for the outback and Eureka for its metropolitan cities.
