The global subscription television service market will grow 19 per cent over the next five years on cable, satellite, and IPTV platforms, research firm ABI Research said Tuesday. The firm issued new data and said in a release Wednesday that cable TV will maintain the largest share of the market through 2017 “although it is losing market share to both satellite and IPTV.” North American cable companies have experienced falling subscriber bases in the past few quarters, the firm said, and cable TV market share globally will drop one percentage point in 2012. “Growth in satellite and IPTV services in North America comes at the expense of cable. This competitive shift, coupled with a small drop in pay-tv penetration, led cable-TV revenues to fall about 1% in 2012 despite a small increase in ARPU . Global Cable-TV service revenue market-share is expected to drop to 47% in 2012 from 48% in 2011,” Jake Saunders, vice-president and practice director of core forecasting, said in the release. ABI Research said it expects subscription TV revenues to reach $236 billion US by the end of 2012, up from $223 billion US in 2011, The firm forecasted the broadcast distribution market market to grow 19 per cent over the next five years, generating $281 billion US in revenues in 2017. U.S. satellite broadcast distributor DirecTV led ABI's global satellite TV market share ranking at the end of the second quarter of 2012 based on its subscriber numbers and revenues, the release said.
