Lots of companies are often swallowed up whole by larger players in the travel sector, never to be seen or heard of again.
But for every Ruba (Google, May 2010), Zoombu (Skyscanner, January 2011) or WanderFly (TripAdvisor, October 2012), whose people or its product swiftly disappeared, others do eventually emerge in some way.
Nine months after TripAdvisor bought ZeTrip for an undisclosed fee, the company behind travel journal application Rove, travellers can now see the results.
Launching this week, TripAdvisor has put a new feature into its mobile app so that users can track and share "experiences" from a trip.
Travel Timeline then creates a record of the user's journey, including photos and a map which can then be shared around the usual social networks.
The feature will only be available for the iOS version of the app.
But the product is essentially Rove, but the usual TripAdvisor branding and associated bells and whistles.
TripAdvisor has been interested in this area for quite some time, having acquired EveryTrail in February 2011.
EveryTrail was also an app-based service which tracked a user's movements around a city and allowed them to create a written and visual journal of their trip.
CEO Joost Schreve later became vice president of mobile at TripAdvisor and now runs operations out of his original Silicon Valley base.
ZeTrip, a fellow West Coaster, integrated with the same team after the acquisition earlier this year.
