12. The radio of claim 10 wherein said analog audio signal has an amplitude, and said amplifier comprises an amplification circuit for increasing said amplitude.

13. The radio of claim 10 further comprising a housing and wherein said amplifier further comprises a first acoustic system mounted substantially inside said housing.

14. The radio of claim 10 wherein said amplifier comprises an outlet for providing said analog signal to a second acoustic system substantially outside said housing.

15. The radio of claim 10 further comprising a buffer unit for temporarily storing data transmitted by said wireless system.

16. The radio of claim 10 further comprising a transmitter for sending ID data to said wireless system.

17. The radio of claim 10 further comprising a display screen for making visible a menu of at least one audio offering.

18. The radio of claim 17 further comprising at least one menu navigation button for designating one of said of at least one audio offering.

19. The radio of claim 18 further comprising at least one selection button for selecting said designated audio offering.

20. A method for transmitting asynchronous audio program data to at least one mobile interactive radio via a wireless system, wherein said audio program data is substantially continuous, said radio having a corresponding subscriber and a subscriber ID, said method comprising the steps of:

receiving ID data comprising said subscriber ID and an audio ID corresponding to said audio program data;

transmitting a first portion of said audio program data in a packet format to said radio via said wireless system, wherein said radio converts said first portion of said audio program data to audible form;

transmitting a second portion of said audio program data in said packet format to said radio via said wireless system after said radio has converted said first portion of said audio program data to audible form.

21. The method of claim 20 wherein said ID data is received from said radio.

22. The method of claim 20 further comprising the step of:

authorizing said subscriber to receive said audio program data before said step of transmitting a first portion of said audio program data.

23. The method of claim 22 wherein said step of authorizing comprises the step of:

cross-referencing said subscriber ID with a database of approved subscribers.

24. The method of claim 20 further comprising the step of:

providing said subscriber via said radio a menu of at least one audio offering corresponding to said audio ID before said step of receiving ID data.

25. The method of claim 24 further comprising the step of:

receiving a menu request code sent by said subscriber before said step of providing said menu.

26. The method of claim 24 wherein said at least one audio offering corresponds to audio program data selected from the group consisting of news, sports and music data.

27. The method of claim 20 further comprising the step of:

confirming that said received audio ID is proper after said step of receiving.

28. The method of claim 20 wherein said audio ID corresponds to real-time audio program data, said method further comprising the step of:
