Cleveland Abbe
In order to compile his information, Abbe required a time-keeping system that was consistent among the stations. To accomplish this he divided the United States into four standard time zones. He published, in 1879, a paper titled "Report on Standard Time". In 1883, he convinced North American railroad companies to adopt his time-zone system. In 1884, Britain, which had already adopted its own standard time system for England, Scotland, and Wales, helped gather international consent for global time. In time, the American government, influenced in part by his 1879 paper, adopted the time-zone system.
East Coast bias
The North American continent is divided into seven time zones, spanning 6½ hours from Alaska to Newfoundland. Most of the continent's population (including all of the major professional sports teams) is concentrated in the four time zones of the contiguous United States and Canada west of the Maritimes; this, however, still poses a significant obstacle in that the easternmost sports teams are a full three hours ahead of their western counterparts. For sports that play in prime time according to local time zones (as is the case with ice hockey, baseball, and basketball), this can result in games played on the West Coast starting after 10 p.m. Eastern time (and not ending until around or after 1 a.m.), while the East is sleeping and after printing deadlines for the next day's newspapers have passed. Gennaro Filice of SI.com wrote that Major League Baseball's West Coast night games are ending as "the country's most influential scribes are catching Z after Z." John Buccigross of ESPN notes that a lot of people in the East are asleep when National Hockey League's West night games are going on, resulting in lower television ratings for those West Coast games, which in turn contributes to the lack of national broadcasts of West games.
