Would be much more useful if phone manufacturers still included FM
radios in the phones rather than some data sucking app that
requires pointless registration in order to listen to stuff thats
free over the air. Not that the BBC are alone in that, News UK and
Global apps do the same shit now

Can’t time shift with FM, most of our listening isn’t done live anymore
.
Post by M***@DastardlyHQ.orgWho's "we". The Radio 2 breakfast show still gets 7 digit listening
figures and is biggest radio show by listener numbers in europe.
Many other stations have figures in 6 and 7 digits too.
Those figures include internet streaming these days.
Some, not most. Plus its a hideously inefficient way of distributing
broadcast audio but no one seems to care about that.
It's a very efficient way, much easier and cheaper than keeping
transmitters operating around the country.
In network terms it’s inefficient to send the same stream of data in
parallel to lots of different clients. Internet multicast, where a
server sends out a single stream and it’s duplicated at branches where
clients request it, is much more efficient, but it’s complicated to
implement and raises a host of security issues.
And what do you think traditional radio broadcasting does?
It doesn't just send the same stream of data to lots of different clients,
it sends it to lots of places where there are *no* clients interested in
receiving it. You take literally megawatts of power, and then blast it
out into the ether at full power on the offchance there is anybody around
to hear it.
And these days, it's fairly unlikely that there is.
(At least cellular radio systems only[^ note 1] transmit when there is
someone listening - and regulate the power of those transmissions to use
the minimum required.)
There is a lot to be said for traditional broadcasting, but efficient
isn't one of them.
I mean, to put some numbers on that, Radio 1 is currently blasting 4000
watts of power into the ether from Crystal Palace tower, 24 hours a day,
whether anyone listens or not. (As an aside - one analogue TV channel
from the same transmitter would have been broadcast at 1000 kW; digital is
a fraction of that but still big.)
But Radio 1 isn't just blasting those 4000 watts from Crystal Palace. The
Arqiva transmission network is 1,500 transmitters, approx. If every one
of those transmitters were broadcasting Radio 1, at the same power as
Crystal Palace (which they probably aren't of course - and many will be
transmitting much louder to cover big areas of low population, unlike
Crystal Palace which is practically the ideal spot for efficiency - but we
can get an order of magnitude), you're looking at in the order of 6
Megawatts of power being blasted into the atmosphere, 24x7, whether
anybody listens or not, for just one radio station. (I would say, while
this is of course the back of an envelope calculation, it's in the right
kind of order of magnitude to match the numbers on the eletricity bills
back in the day when I had a radio station to worry about.)
It's many things, but you call that *efficient*?
[^ note 1]: pedants, fuck off. Yes they transmit things like timing and
control signals all the time, but it's incredibly low-power and we can
ignore it for the comparison with broadcast radio.
