StevensOnln1: Well, if that's the case, it's incredibly inefficient, costly, and ultimately, unworkable.
With their moans and groans about how few billions we pay them to provide television, how can it be justified?

StevensOnln1: Well, perhaps you can enlighten us on how it's technically possible to deliver millions of individual streams - which is the question I asked in the first place.

Meanwhile:
Unicast
In computer networking, unicast refers to a one-to-one transmission from one point in the network to another point; that is, one sender and one receiver, each identified by a network address. More at "Wikipedia"
Multicast:
In computer networking, multicast is group communication where data transmission is addressed to a group of destination computers simultaneously. Multicast can be one-to-many or many-to-many distribution ... More at "Wikipedia"

Chris.SE: Thanks again. So, given that an iplayer stream is 5Mbps, we have 5Gbps per 1000 and 5Tbps per million - the engines won't stand it captain! Well, maybe a million, but 20 million?
Searching for "BBC multicast" brought me to an interesting page:
"Multicast streaming
By combining multicast distribution to edge caches with unicast distribution downstream we are also able to support the large installed base of standards-based unicast media players. And using this hybrid model we can even support product features such as "live restart" in a scalable manner."

Presumably "live restart" is what we've been discussing. I'm not sure what "in a scalable manner" means.
An early BBC attempt at using Multicast "a smarter way of serving large numbers of people" is here:

StevensOnln1: Like a youtube live stream that has rewind enabled? Wouldn't that require personal streams?
