Re: First Names, and username origins
It's how network television works in the United States. We have four major networks and two minor networks, plus PBS (public TV) and a whole bunch of cable channels. The four major networks are ABC, NBC, CBS, and FOX. The two minor networks are WB and UPN. Each network broadcasts is shows at a given time, Eastern time. (US is made up of four different time zones, to complicate things.) Each city (or technically, a "viewing area" (composed of about a fifty-mile (100 km) radius) has its own affiliate for each station. An affiliate is its own TV station that airs its own local news, sometimes programming of local interest, etc. During primetime (and sometimes daytime) it also airs the shows of the national network it is affiliated with.
For example, Fox 35 airs its own local news at, say, 6pm, then airs local programming (usually repeats of some old show) at 7pm, then airs nationally shown Fox shows at 8pm, then airs another local news segment at 10pm.
Hope that makes sense.
