In the world of television, does anybody know what exactly is "sweeps?"
You can leave an optional "tip" with Mahalo's virtual currency, Mahalo Dollars. If you are asking a difficult question that might require some research, or if you'd like a wide variety of feedback, a higher tip often leads to more answers to your question.

Wiki has a bit more:
Diaries are also used to collect viewing information from sample homes in many television markets in the United States, and smaller markets are measured by paper diaries only. Each year Nielsen processes approximately 2 million paper diaries from households across the country for the months of November, February, May and July — also known as the “sweeps” rating periods. Seven-day diaries (or eight-day diaries in homes with DVRs) are mailed to homes to keep a tally of what is watched on each television set and by whom. Over the course of a sweeps period, diaries are mailed to a new panel of homes each week. At the end of the month, all of the viewing data from the individual weeks is aggregated.
This local viewing information provides a basis for program scheduling and advertising decisions for local television stations, cable systems, and advertisers.
In some of the mid-size markets, diaries provide viewer information for up to three additional “sweeps” months (October, January and March).

M$Normally it is during these times when you will see more special effects, special guest star appearances and twist and turns within shows. Other surprises during Sweeps might be one of the shows stars getting shot or killed off or leave the show. All of these things are done in hopes of gaining your loyal following.
