Mostly, I think, voting systems designed to ensure that parties get a share of seats that’s proportional to their number of votes (“party-list proportional representation” is what Wikipedia calls it). E.g. the D’Hondt method seems pretty popular (and is used in Finland as well as several other countries).
As for whether it’s actually better overall—well, I grew up with it and am used to it so I prefer it over something that would produce a two-party system. ;) But I don’t have any very strong facts to present over which system is actually best.
