The commercial non-PSB sector saw strong growth in share of total TV viewing of close to 40% as the multichannel TV homes universe doubled in the 10 years between the launch of Freeview in October 2002 and completion of digital switchover in October 2012, and even higher 50% growth in SOCI (share of commercial impact) thanks to the higher commercial airtime quotas of the non-main PSB channels
Even during the growth years, non-PSB channels that were present in 2003 felt a squeeze on viewing share and suffered losses as result of numerous channel launches that added to the long tail (Squeeze 1), and strong growth in the PSB families (Squeeze 2), which saw the total PSB share among the Top 25 channels in multichannel TV homes rise from less than 80% to over 90% between January 2003 and January 2014
Today, both the PSB and non- PSB commercial channel groups face the challenge of internet connectivity and increasing population of portable screens (Squeeze 3), and they are experiencing similar rates of decline.
