it's not an isolated case. in general European animated series tend to last long. 10+ years is not uncommon, although usually with long gaps. the main reasons are:
1) we have protectionist laws that force TV networks to fund and air a certain proportion of European content.
2) much less concurrence than in the US, especially since by the above law European series fight in a category of their own, so the renewal threshold is low.
3) a great part of the funding of European animated series comes from public subventions, which are much easier to renew than landing initially (even if the ratings are not that strong)
