The discovery of widespread multiple stellar populations in globular clusters has forced us to change dramatically our vision of these objects and of their formation. Especially intribuing has been the realization that some of these populations are strongly enriched in helium. The many suggestions so far advanced on the origin of the multiple populations will be reviewed and confronted to updated observational constraints in the attempt to identify those which may remain viable.
