coaches in their respective sports, although there are some exceptions. The term "color" refers to levity and insight provided by analyst. The most common format for a sports broadcast is to have an analyst/color commentator work alongside the main/play-by-play announcer. An example is NBC Sunday Night Football in the United States, which is called by color commentator Cris Collinsworth, a former NFL receiver, and play-by-play commentator Mike Tirico, a professional announcer. In the United Kingdom, however, there is a much less distinct division between play-by-play and color commentary, although two-man commentary teams usually feature an enthusiast with formal journalistic training but little or no competitive experience leading the commentary, and an expert former (or current) competitor following up with analysis or summary. There are however exceptions to this — most of the United Kingdom's leading cricket and snooker commentators are former professionals in their sports, while the former Formula One racing commentator Murray Walker had no formal journalistic training and only limited racing experience of his own (he had come from an advertising background and his initial hiring was more of a comic double act than a traditional sports commentary pairing). In the United States, Pat Summerall, a former professional kicker, spent most of his broadcasting career as a play-by-play announcer. Comedian Dennis Miller's short-lived run as part of the Monday Night Football booth in 2001 caused what Miller himself described as a "maelstrom" of perplexed reviews. Although the combination of a play-by-play announcer and color commentator is now considered the standard, it was much more common for a broadcast to have only one play-by-play announcer working alone. Vin Scully, longtime announcer for the Los Angeles Dodgers, was one of the few examples of this practice lasting into the 21st century until he retired in 2016. The three-person booth is a format used on Monday Night Football, in which there are two color commentators, usually one being a former player or coach and the other being an outsider, such as a journalist (Howard Cosell was one long-running example) or a comedian (such as the aforementioned Dennis Miller). Sideline reporter A sideline reporter assists a sports broadcasting crew with sideline coverage of the playing field or court. The sideline reporter typically makes live updates on injuries and breaking news or conducts player interviews while players are on the field or court because the play-by-play broadcaster and color commentator must remain in
