ABC began broadcasting the Open in 1962, with taped highlights on Wide World of Sports. In the pre-digital age the coverage had to be converted from the U.K.'s PAL colour encoding system, to the U.S.'s NTSC, which meant picture quality could be impacted, especially in the early years. The coverage expanded over the years, and as is common in America, there was a different early round rights holder, which was ESPN until 2003 when TNT took over. Co-owned ESPN became responsible for ABC's sports coverage in 2006; it won the rights to cover all four days of the championship in 2010, and concurrently moved coverage to its channels. The Open became the first golf major to be covered exclusively on pay television in America, as ESPN left only highlights for its partner broadcast network.
