...Got one of those mass BlueTooth senders like some stores have and gone to a massive gig and sent out a message to visit your site? I write about wrestling and can imagine going to an 80,000 Wrestlemania event and telling them to all visit my site. Is it even possible?
No idea if it's possible, but you might have a few problems getting one of them senders into a gig past security! If you could do it though, you could get your brilliant results.
I don't think it works that way, as the people need to accept your message and have BlueTooth turned on. But sure, you might be able to get a few hundred sent out
I know someone who does this with a different sporting event. He doesnt bring the unit into the event, rather he parks in his car outside the event and then broadcasts when the crowd is leaving. These devices are expensive though..
