Live television is often used as a device, even when it is not in various types of programming to take advantage of these often to great success in terms of attracting viewers.[citation needed] The NBC live comedy/variety program Saturday Night Live, for example, has been on that network continuously since 1975 and airs live in the Eastern & Central zones during the show's season which runs from September though May.
On September 25, 1997, NBC broadcast a special live episode of its hospital drama ER, which at the time ranked as the third most-watched episode of any medical drama program ever. Many television news programs, particularly local news ones in North America, have also used live television as a device to gain audience viewers by making their programs appear more exciting. With technologies such as production trucks, satellite truck uplinks, a news reporter can report live "on location" from anywhere where a story is happening in the city. This technique has attracted criticism for its overuse (like minor car accidents which often have no injuries) and resulting tendency to make stories appear more urgent than they actually are.
The unedited nature of live television can pose problems for television networks because of the potential for mishaps. To enforce the Federal Communications Commission (FCC) regulations, television networks often broadcast live programs on a slight broadcast delay to give them the ability to censor words and images while keeping the broadcast as "live" as possible.
