It would very difficult to put your finger on something that significantly altered in 2014.
Yet perhaps the pivotal moment isn't a moment at all, but a sense.
Airbnb, Uber and HotelTonight, for example, all matured into services that real consumers have heard of (and use).
Travel startups that previously traded on high risk high reward, highly funded innovation, instead focused on building up key cross industry services that consumers, suppliers or others actually have real use for (and are willing to pay for).
This arguably shows a maturating of the entrepreneur mindset across the industry.
Companies (such as deal websites) and individuals (such as travel bloggers) who traded in gaps left by existing players also reached a peak (and may now wane going forwards), as incumbent services mature and take back the ground they previously lost to more nimble, tactical players.
Perhaps history will judge 2014 as a moment when digital became mature. Difficult to say that now, but perhaps in a few years time we will be able to say that about 2014.
What does this potentially say about next year, then?
I expect the pivotal moment to be something that comes out of left-field, as we are overdue a shake-up of some kind.
If you think about the three main changes to hit the travel industry in recent times (web, social media, mobile), all have come from outside the travel industry, not from within. Like volcanic eruptions, its just a matter of time until it happens again.
What could that next big thing be? It could be BitCoin (unlikely), it could be wearables (too soon) - so, I would actually go for iBeacons.
Someone will do something great, in destination, using iBeacon technology.
2015 will be the year that we start talking about trip spontaneity rather than trip planning.
