About 27% of all TVs shipped in Q1 were equipped for Internet access, according to market tracker NPD DisplaySearch. Nearly 20% were so-called smart TVs, defined as those able to access a branded portal or service, rather than just publicly available platforms such as Google's (GOOG) YouTube. Japan was the No. 1 market for Internet and smart TVs at 46% and 36%, respectively. Sony (SNE) was the brand leader, with half its Q1 units smart TVs. Apple (AAPL) is rumored to be working on its own smart TV.
