The definition of socialism does not change and has not changed, and it's not "social democracy".

Many European political parties that have "socialist" in their names are historically socialist but have all but abandonned that ideology in favour of social democracy (i.e they have moved right) because, as we know, socialism was tried and it failed so there has been a lot of soul-searching on the left since the fall of the USSR and al.

That does not mean that there aren't socialists anymore, including in major parties.
