From the beginning of the Internet age, these organization were some of the first to create web sites. When I first got access to the Internet in the early 1990's, the global aspect became immediately apparent. I was spinning actual hard discs on computers in the countries I was researching. Note the dead links in the inclusion of the 'Where in the World' section on this archived copy of my personal site from the mid-1990's. The letters 'www' quickly started to supplant much of the need for the post office.
Of course in the last 15 years there's been no looking back. Tourist boards only publish fine, paper brochures for a niche markets; namely, destinations popular among people so old as to not know their way around a keyboard. For the rest of us there's plenty of .html and .pdf information available 24/7.
The other day I did pick up a Lonely Planet guide to Central America at our library. That became a springboard for additional online research. It is a relatively close destination but I'm sure I couldn't have matched the countries' names to their shapes on a map. Now, there's more online information to read than would fit on the postal service's largest trucks. Imagine, now I can even spread video content designed for tourists right here on a personal blog.
La tecnología es grande.
