its face, may also feature either a traditional mechanical scoreboard, or a scoreboard display within a LED display on the front of the table which also functions with virtual scrolling advertisements. Since 1991, the NBA has mandated that each shot clock carry a duplicate readout of the time left in the period in addition to the shot time. Since 2011, the shot clock also shows tenths of a second past five seconds left on the shot clock. Many college and even some high-school shot clocks (in states where a shot-clock rule is in effect for high-school basketball) now also include a game timer. Three-sided game shot clocks became a trend in the 1990s, and after a controversial series of calls during the 2002 NBA Playoffs, the NBA instituted a new game shot clock rule in 2002, requiring specific visibility of the game- and shot-clock time for instant-replay purposes. FIBA installed a similar three-sided rule in 2004. The rule was further changed in 2005 by permitting a new Daktronics see-through model (one on top of the basket, one on the end of the basket unit) that has gained popularity as many OES and Daktronics venues have adopted the system. Daktronics has introduced a technology called ColorSmart, which denotes the trailing team's score numbers with red lighting, while the leading team is in green. However this technology has yet to be utilized in a game settings as the bylaws of the major basketball sanctioning bodies and many of the high school athletic bodies decree that both scores must display in the same color; the rule came into effect in 1994 after Spectrum Scoreboards introduced an earlier version of the concept. This is used almost exclusively in recreation leagues. Baseball For baseball the scoreboard will at the minimum show both team scores, as well as the current inning. In addition the number of balls, strikes and outs is represented by digits or individual lights. Larger scoreboards offer an inning-by-inning breakdown of the scores, hits, errors, pitch count and the time of day, along with pitch clocks for leagues which mandate that rule. There may also be another display either separate or combined with the scoreboard listing the radar gun reading of the last pitch thrown in miles per hour. Almost all Major League facilities have a video board as a scoreboard or a matrix display. Usually these scoreboards are controlled via programs that
