16 million people watched that press conference on BBC TV, broadcasting is very efficent at getting live pictures out. The BBC did experiment with multicast in the past, but CDNs seem to be a more scalable solution ironically.
However in this specific case, the pictures actually left downing street via multicast (SDI form camera into encoder, MPEG-TS over multicast to the studio, back to SDI to get encoded on whichever output chain it is - Terrestial, Satelite, Cable, online)
Indeed the standard to replace SDI (2110) is built around multicast, broadcast certainly uses multicast a fair bit.
