FM complemented by Internet
FM radio is not going away. Not in the foreseeable future. It works very well for almost everyone, almost everywhere—about 99%.
The BBC is increasing their DAB coverage from about 86% to 90% in 2011—with about double the transmitters and double the physical network and transmission costs—under the current license fee agreement. Commercial radio has not committed financially beyond their current 86%. They are struggling to pay for that (leaving transmission slots to specialist stations for short terms).
To get to 95% DAB coverage is about another doubling in transmitters and costs. To get to about the same 99% DAB coverage as FM is another doubling in transmitters and costs. Neither the BBC nor commercial radio can pay for expansion to 95% or 99% DAB without Government authorization, financial support—which seems increasingly unlikely. In the meantime, participants’ licenses get extended, devices get sold, and leadership remains respected and funded. Facts get short shrift, dissed. http://grantgoddardradioblog.blogspot.com/2010/06/cost-of-upgrading-dab-radio-why-it-will.html
Internet radio complements terrestrial radio—all broadcast systems, analog and digital: FM, AM, MW, DAB, DAB+, DMB, HD, etc. Internet radio adds location-shifting and time-shifting—wherever you are, wherever they are, and whenever.
Broadband, mobile broadband, Wi-Fi and 4G are driving Internet access and use wider and deeper in our lives. Including Internet radio. Capacity for Internet radio, particularly as a complement to FM, is not a problem—only declared one by the DAB protagonists. (Video, with much greater promotion, is more than 10X more difficult.)
