[ WP ] In a futuristic world , you can relive any memory through advance simulation . However , the only downside is that you will lose that memory once the simulation ends .

Even now, I still do n't know how I could have made billions off such a simple scheme. Really goes to prove that high tech makes people stupid, eh? 
 
 I'm sure people imagine my greatest achievement to be the invention of pRecall, the simulation system that allows people to re-enact their memories. But to me, it was never about the technology. Technology was always just pieces of metal or wire coupled with some arbitrary ordering of bits and bytes. No, my greatest achievement was to corner the market, to make my business the largest and most successful on the block. 
 
 I was n't even the first mover. There were already companies on the street that offered re-enactment simulation. But those companies were almost always founded by engineers and scientists rather than businessmen. As such, they were fatally anchored by their technology. They were expensive, required extensive setup per simulation session, involved potentially dangerous neural interfaces, and could only simulate a window of up to 30 seconds, and not even at real time. I saw a weakness in the market, and I moved in. 
 
 My product pRecall was designed to exploit those weaknesses. Instead of useless 30 second windows, I offered exposures in blocks of 90 minutes and up. pRecall did n't require any extensive setup, merely a short psychological prep session where the user described what he wanted to relive from his memories. Instead of intrusive neural interfaces, pRecall was administered via an oral pharmaceutical preparation. Above all, it was cheap. The everyman could afford it. I marketed it as something that everyone could enjoy regularly. 
 
 Sure, pRecall, despite its name, never actually allowed you to retain the memory of the simulation. The user still experienced lingering emotions from the simulation, but the memory itself was lost upon the end of the session, a regrettable side effect of the lossy procedure. But it was still an overwhelmingly superior product otherwise, so people flocked to it. Marketing saw to that. 
 
 I never did patent the technology, did I? I kept it hidden as a trade secret all these years. There's a reason for that, if you think about it. Have n't you wondered about it? Why even today, there are no competitors with technology even remotely approaching what pRecall can achieve? 
 
 Heh, then again, what does pRecall achieve? 
 
 A memory simulation where users lose their memories of the simulation after the session. How convenient. 
 
 The pharmaceutical preparation was simply a drug to induce dreaming sleep, laced with whatever stimulants to invoke the expected emotional response. The psychological prep session was simply to allow the user to fill in their own mental blanks, to let them feel reconnected to their memories. 
 
 Therefore, I have always asserted that the secret of pRecall was my incredible business sense.
