Taplands is the nickname for lands that produce multiple colors of mana and generally enter the battlefield tapped during some point in the game and have no additional drawbacks, though mechanics to have these lands enter the battlefield untapped may be present. This is the most common drawback given to lands, thus a multitude of cycles of such lands was created over the course of several years. Strangely enough however, such lands were considered "too good" for a long time, until Randy Buehler suggested them during one of his first development meetings for Invasion after joining R&D.
However, the very first cycle of taplands was an enemy-colored cycle of lands that appeared in Tempest, which have an additional drawback of 1 damage and thus may also be categorized as Painlands as well as taplands. 
The following is a list of cycles and individual cards considered true taplands.
Another cycle which functions similar was released over the course of Ravnica block. However, these lands were also Dual lands with basic land types and had the option to come into play untapped if their controller paid 2 life. Colloquially they are often referred to as Shock lands. Rather than five lands, this mega cycle included ten cards, one for each color pair.
This cycle was later reprinted in Return to Ravnica block.
In Lorwyn block a loose array of lands was produced which came into the battlefield tapped unless its controller revealed a creature card of a certain creature type from hand. These lands do not follow a strict color cycle like other taplands do.

Return to Ravnica block included a new cycle of taplands, one for each guild colors combination. Those new dual lands function like the Invasion taplands, except the addition of the Gate subtype on them which is also included in some cards of the block for additional effects. Rather than five lands, this mega cycle included ten cards. 
Theros block included a new cycle of taplands, with the added benefit of letting the player Scry 1 when they enter the battlefield. The five lands in Theros share their colors with the Gatecrash guilds, and the cards of the remaining colors were split between the other two sets.
