"The Bachelor" is a reality television show in which one man chooses his future wife from a pool of eligible women. Over the course of the season, the bachelor goes on dates and vacations with these women, gradually eliminating those he does not see as potential wives at the end of each episode. Once he narrows his selections down to two women, he proposes marriage to one of them in the final episode of the season.
The formula changes slightly from season to season, but generally "The Bachelor" starts with a group of 25 women and eliminates one per episode during the Rose Ceremony, in which he gives a rose to each of the women he intends to keep on the show. The women live together in a house throughout the taping of the show, which results in many dramatic moments as they vie for the bachelor's attention.
As of 2015, "The Bachelor" has aired for 19 seasons on ABC. It has also resulted in a spin-off series, "The Bachelorette," in which the formula is reversed: one woman chooses from a pool of potential husbands over the course of the season. Other spinoffs of "The Bachelor" include "Bachelor Pad" and "Bachelor in Paradise."
