What ELSE happened during the 25 years of online travel?

The Guardian newspaper in the UK asked us this week to pull together some of the milestones of online travel in the 25 years so far of the web.

How 25 years of the web inspired the travel revolution was the result, covering everything from the birth of the world wide web itself to the present day.

These are the major points we picked out:

1989

Jeff Greenwald posts what is later claimed to be the first travel blog.

1996

1998

Lastminute.com becomes the iconic ecommerce brand of the period, launching its playful online travel agency in Europe.

1999

FareChase triggers what eventually became a major online travel shopping process - metasearch. Led to Sidestep, Skyscanner, Kayak et al.

The pizza parlour-dwelling review service TripAdvisor is launched - hotels were never the same again.

2001

One of many unintended consequences of the September 11 attacks materialises as suppliers realise the web is a significantly efficient way of shifting unfilled inventory.

2004

Priceline starts heading down the road on which it eventually gives it a mighty position in the travel ecosystem - buying Active Hotels and then Booking.com a year later.

Harvard student Mark Zuckerberg launches Facebook, the social network that inspired generations to live their lives (and travels) on the web.

2007

Apple unveils its first foray into mobile communications with the iPhone, bringing access to the web from a handset to the masses. Thousands of travel-related apps follow.

2008

AirBedAndBreakfast (later renamed to Airbnb) leads the charge of a second wave of online travel brands, bringing short-term travel rentals into a web marketplace.

2009

Twitter takes hold and inspires real-time messaging and engagement between travellers and travel brands.

2010

Google ramps up its interest in the industry (beyond taking its advertising spend) and buys ITA Software.

2011

HotelTonight leads the wave of travel brands which probably could not have existed before mobile services kicked in - same-day booking of hotels via a handset.

2012

Europe-based airline KLM decides the only way to figure out how to use social media effectively is to experiment with it - massively. The flagship project being its Meet & Seat service.

So that was our list for the Guardian (read the full version and analysis over here).

But we thought (not least from fielding a a bulging mailbox since the article's publication earlier this week) that there must be countless other moments behind the scenes other or launches on the web which have helped shape the industry over the past 25 years.
