One huge thing that has changed will definetely be fusion power that mankind has harnessed. That is also one of the reasons for the lunar mission. Helium-3 is really the best way to keep the process going.

In sports one might mention Hockey Champions League. It might have became as big as footballs Champions League is nowdays. Also you really shouldn't forget about political incidents (Like Ilkka Kanerva's text messaging scandal).
