I love dipping in and out of this thread, always makes me chuckle
So broadcast TV is slowly dying, that cant be argued. Viewers on average are down and ad revenue is slowly declining, especially in this current Covid world... but heres the deal... Broadcast is so critical to service suppliers like Sky, ITV and others because a huge portion of their income comes from advertising revenue. If these providers move more towards a full on demand service and whittle away their broadcast channels then they will feel the fit in revenue.
On demand is booming, it will continue to overtake the broadcast market but broadcast will probably be here for the very long term. As someone who is actively working on next generation technology that includes broadcast services, i can happily confirm that broadcast TV will certainly be around on the Virgin Media network for many years to come.
