People will get all the information on historic sites and other attractions on their car radio or portable FM receiver; no need to rent and bring back a dedicated, non-standard receiver, which can be cumbersome and impractical.  Decade transmitters can be used for many purposes in amusement parks, zoos and other tourist attractions anywhere around the world.  They can broadcast themed soundtracks and background music throughout the entire site, information on a specific animal in a zoo or a specific attraction, or general information to visitors.
