You can’t simply start making five ads with Jerry Seinfeld, start airing them, decide you don’t like them after a week, film a new ad, and switch the old one out and the new one in within 7 days. I'm pretty sure you can. Most advertising agencies present multiple options to their clients and variations thereon, so Microsoft likely had half a dozen half-fleshed-out ideas they could have followed in addition to the Seinfeld one. And, yes, producing an ad could take a long time, but it could also take a very short time, depending on what is needed and how much money you are willing to throw at it. Every day, news networks come up with hours of professionally produced graphics, interviews, and reports, with lead times varying from a few days to a matter of minutes.
