Back in the late 90s tech boom days McDonalds declared that they would sell hamburgers over the Internet. Remember, this was before smartphones, hell it was before Nokia flip phones with rudimentary browser and email. Most people who had internet access at all used it either at work, school or the family computer with dial up modem.

McDonalds' stock price rose by 50%.

I remember it because I thought this was so stupid that it must mean that the bust was near. I was just of years. The market can stay stupid longer than you can believe it, or however it was Keynes put it.
