It took about 10 years for big companies to jump on the whole 'internet thing' and then even longer for e-commerce. My guess is they'll take to it a little faster now that the world is more comfortable with computers but I don't expect them to just jump on it.
The internet was kind of a no brainer. There was nothing to lose by getting on there at the time.
BTC needs to reach the no brainer level too before something similar happens. I dunno what'll get it there but maybe we'll find out in the next few years.
