Here in Sweden, the tradition is to watch Dinner For One (on TV every year since 1976), get very drunk and then watch fireworks (or set them off yourself and get your fingers blown off if you're drunk enough).
I missed Dinner for One this year, and was rather happy about it. After 30+ viewings it has lost its charm.
My family tradition is otherwise TV-based. Zap around between the plentiful movies, while drinking some coffee and/or gleuhwein. Around 23.30, switch to channel 1 to watch the celebration in Stockholm. Also glance out the window, to see if some sucker has spent so much money on fireworks that they are actually worth watching. Then at midnight, make a few phone calls and go to bed.
Fireworks at New Year are rather new around here, by the way. They used to be reserved for Easter, but at some point in the 1980s or so they started selling in December too.
