According to ABI Research, the worldwide pay TV market will continue to grow to generate service revenues of $236 billion by the end of next year. Cable TV operators continue to face increasing competition from IPTV and over-the-top (OTT) services. Increasing broadband penetration and the growing number of people using Internet-connected devices are supporting subscriber growth in IPTV and OTT services."Cable TV services will still dominate the overall pay TV market, although this segment's market share is expected to slightly decrease from 2011. Cable TV service revenue will account for 48.6% of total pay TV revenue in 2012," said Jason Blackwell, ABI practice director, digital home, in a statement.
