About 21% of the TVs forecast to ship worldwide in 2010 have Internet connectivity, representing about 43.9 million units, according to research firm DisplaySearch -- although today less than half of consumers actually use the Net-connected features.
The category is projected to grow to more than 122 million units in 2014, according to DisplaySearch, a unit of retail NPD Group.
Meanwhile, less than half of consumers (45%) say they use the connected features of their Internet TVs, according to a separate NPD study released this week. Of those who have connected their TVs to the Internet, 57% say they are very satisfied with the TV's Internet features.
Among those who have hooked up their TVs to the Net, 57% are using it to access Netflix, 47% are viewing videos on YouTube and more than half (54%) said they accessed video, music, or photos on their home networks, the NPD survey found.
Earlier this month, embedded security software vendor Mocana warned that it had discovered a major Internet-connected HDTV brand had security holes that could let a hacker take control and trick users into divulging private data. While the firm didn't identify the manufacturer, details in the report indicated the HDTVs were from Panasonic.
