Fifth, one cannot discount as a factor in explaining the new interest in the developing nations the new technologies as well as the funding then available. Technologically, the late –
1950s to early 1960s was the period when widespread jet travel became available on a large – scale basic for first time.

Accommodations abroad, in the form of hotels, rental cars, computers, and travel facilities, also greatly improved. In addition, there was more grant and research money to do these things.
