Internet TV (ITV) is generally-available content distributed over the Internet. Unlike IPTV (Internet Protocol television), which is distributed over proprietary networks, Internet TV is available wherever a broadband connection exists.
The two terms are often confused. Despite its name, however, IPTV is generally not available over the Internet. It's more like a replacement for cable TV with similar offerings and typically offered by the same carriers, for the same types of fees. Internet TV, on the other hand, is available online and is more likely to be free.
Internet TV options include Web-based shows, video on demand (VOD), streaming video and regular television shows hosted on the channel's websites.
