Again, it's about overall revenue and planning. If the media, host nation, or advertisers could gain substantially from having womens ski jumping in the olympics then womens ski jumping would be in the olympics. If they thought a majority of TV's would be tuning in around the world there is no way they would be leaving it out. Obviously, this is not the case, as they did not include it.
'The Majesty, the Pageantry, and the Drama' -- that's what draws the public's interest and makes them watch.
Now, NBC just paid how many billions of dollars for the exclusive rights to cover the Olympics for the North American aduience?
You are the Olympic coordinator at NCB sitting their thinking, "I am going to milk this thing for everything it's worth. Advertisers are going to pay us five-million for a sixty-second ad during figure skating. On the other hand, I am going to find it very hard to milk womens ski jumping."
Now, the IOC planners and host nation are going to consider this, along with the other factors noted above, when deciding what events are prudent to include and which are not.
This is not ancient Sparta and athletes are not running around in loin cloths wearing wreaths around their heads. For the most part, the Olympics are about revenue. Athletes want to compete and win just for the sake of winning, but they also want to increase the advertising potential which comes from competing in the Olympics. The Media wants the advertsing revenue that comes from showing the events. The viewer wants to see 'the Majesty, the Pageantry, and the Drama' and will patiently sit through the sixty-second ads for which the advertisers paid top dollar.
