Paragraphs:
Retail TV
(1) As of January 1, 2019, we are no longer reporting wholesale subscribers in our TV subscriber base reflecting our focus on the retail market. Consequently, we restated previously reported 2018 subscribers for comparability.
Retail IPTV net subscriber activations decreased by 17.4% in 2019, compared to last year, resulting from the impact of a maturing Fibe TV market, slower new service footprint growth and greater substitution of traditional TV services with OTT services, partly offset by higher Alt TV activations.
Retail satellite TV net customer losses improved by 4.3% compared to 2018, attributable to lower deactivations, reflecting a more mature subscriber base geographically better-suited for satellite TV service.
Total retail TV net subscriber activations (IPTV and satellite TV combined) decreased by 71.9% in 2019, compared to last year, due to lower IPTV net activations, moderated by fewer satellite TV net losses.
Retail IPTV subscribers at December 31, 2019 totaled 1,767,182, up 5.5% from 1,675,706 subscribers reported at the end of 2018.
Retail satellite TV subscribers at December 31, 2019 totaled 1,005,282, down 7.8% from 1,090,705 subscribers at the end of last year.
