<p>IPTV sites are platforms that allow users to access live TV channels, on-demand shows, and movies online. Some sites act as IPTV providers with subscription plans, while others offer free IPTV streams (often of questionable legality). The best IPTV sites provide stable HD/4K streams, a clean interface, and compatibility across multiple devices. Popular legal IPTV sites include Sling, Hulu, and YouTube TV in the USA. When choosing IPTV sites, always ensure they are licensed, as illegal platforms may risk shutdowns, poor quality, or security issues.</p>
