How long does it take to download wow

It depends on your internet connection: the whole base takes 4 DVDs (4.7gigs). That's about 18.8 gigs or 18,800,000,000 bytes. On my DSL at home I can get about 600,000,000 bytes in 2 hours, so its 300,000,000 bytes per hour. 18,800,000,000 bytes / 100,000,000 bytes/hr ~ 62.5 hours or 10 hours just shy of 3 days (approximately 2 1/2 days.)

On a 56k modem that would be about 52 days.
