all I see in the media are scandals, the fact that cities are either dropping bids or not bidding at all, and if you ask a random person in most of the world, chances are the person will like to watch olympics but won't want the Games in his/her city.
are we watching the end of an Era? Olympic brand is obviously still very powerful (is there any brand more recognizable than the rings??) but i feel we are watching its decline.
at the same i've seen the media report and apparently Rio Games was a huge success again (at least financially and with records of viewers and contracts rising). IOC has signed with Alibaba.com as a world wide partner recently and the sponsors are safe for Tokyo 2020 and no doubt they will be for Paris/LA.
in the end, are people losing the interest to watch Olympics? Could we watch the end of the Games in like 20 yrs, or this is just a crisis moment that will be surpassed?
