What happened to travel shows?

There are 2 kinds of travel shows that have been on UK tv. The travelogue which features the presenter going on a trip to a location and relate to the audience certain facts, opinions and anything that will interest the audience, this has featured the likes Jerome Flynn, Michael Palin, Joanna Lumley and Michael Portillo. Some of these have themes like Portillo's railway journeys. The other kind is that of the show that would feature reports, news and opinions, the 2 most famous examples being ITV's Wish You Were Here and BBC1's Holiday (whatever the year was) although there were others that came and went. ITV axed Wish You Were Here in 2003 in order to show Emmerdale from Monday to Friday at the same time while Holiday was axed for a similar reason in order to make way for The One Show in 2007. Some will point to the abundance of Travel Channels that have presenters talking about the latest offers but they do not feature reports. The problem I have with the current crop is that they tend to be more about the presenter than the location, with the old school you got more than a flavour and you felt you were there. Perhaps with travel being more affordable perhaps that is the reason for the decline
