I never even <i>mentioned</i> economics, thus your comment does not in any way disprove <i>anything</i> I said.<p>In your example, the employer buys time, not information. Time is significantly harder to reproduce or copy than information is.<p>So, one way to charge for information is to sell time sensitive information (like stock information), but then what you're really selling is time exclusivity.<p>Selling information without any kind of unique or time sensitive properties is doomed to fail — the only thing that made it once possible was technical limitations; information needed for instance paper as a vehicle to distribute it. Those technical limitations are gone now.
