Reported in various sites. Broadcast says:
Freeview has now passed the 100 million mark for the number of digital terrestrial television TVs and boxes sold since its launch in 2002. The figure includes all televisions, set-top boxes and DVD and Blu-ray devices with an inbuilt Freeview DVB-T SD or HD tuner.Integrated digital televisions (IDTVs) make up the majority (66%) of Freeview units sold, at just over 70 million. Freeview+ digital TV recorders account for over six million sales.
HD televisions and boxes account for 16 million sales and have seen year-on-year growth since Freeview HD was launched in 2010. Of these, 98% of sales were TVs.
What none of the reports seems to mention is that there seems to be no particular reason to expect this growth rate to continue. DSO is done and dusted. HD may be keeping set sales active so far but may not be a strong enough incentive, for a lot of people, to justify an early expensive upgrade. Freeview Play even less so, as it is coming late to the streaming party and (apparently) offering only PSB catchup. And 4K is fine except there's very little to actually watch and it does pose a problem for catchup.
My guess - we may have reached peak Freeview. Or nearly.
