Elixir Strings rule the extended-play string market. They are brought to you by W.L. Gore and Associates, an innovator in PTFE polymer since 1958 (think Teflon). If you're a skier and a hiker like me, you've probably used Gore-Tex clothing for years. Now, they turn this expertise to making polymer coatings for their Elixir guitar strings, and the results are striking. You don't have to spend long in any guitar-related discussion before someone eventually begins praising the long-lasting tone of Elixir's acoustic strings (or electrics, or bass, or any other of Elixir's many varieties). Whether you're looking for the mellower tone of Polywebs, or the straight from the box brightness of Nanowebs, Elixir is bound to have a string that will suit your instrument, and dramatically decrease the frequency with which you have to change strings.
