Before there were time zones, each city kept its own time, with noon being the time when the sun was at its highest point over that city (plus or minus an "equation of time" offset to make each calendar day equal). So in a sense there were as many time zones as there were cities. That became increasingly more difficult to deal with as communication and travel became increasingly faster.
The International Telecommunication Union (ITU) is the organization that determines and regulates worldwide time zones. The ITU coordinates with countries to establish and maintain accurate timekeeping standards for different regions.
No, a show airing in different time zones will typically be broadcast at the same local time across each time zone. This means viewers in different time zones will see the show at different times based on their local time.
At any given time, the clocks around the world are set to at least 38 different times, and these time zones have about 165 different names, including about 130 different names just for Standard Time designations.
Time zones were crested to have the local time correspond with the amount of daylight hours there are. The sun sets and the daylight hours fade at different times in different places. With time set up to correspond with this it creates different time zones.

No, the Railroads did.

BPOs work at night due to different time zones, as they work in countries which have different time zones.
there on a time line
yes
The United States was the first country to establish the world time zone. The time zones were created in order for the railroads to standardize their schedules.
Planets have different time zones due to their rotation on their axes. As a planet rotates, different regions are exposed to sunlight at different times, causing variations in local time. This is why different regions on Earth have different time zones based on their position relative to the Sun.
Cities in different time zones have different times.
