Uncontacted tribes are a source of fascination in "contacted" society, and the idea of tour operators offering extreme adventure tours to specifically search out uncontacted people has become controversial. A BBC Four documentary in 2006 documented a controversial American tour operator who specializes in escorted tours to "discover" uncontacted people in West Papua, similar to the BBC's own adventure in Papua New Guinea to make its 1971 documentary A Blank on the Map in which the first contact in over a decade was made with the Biami people.

The Sentinelese continue to actively and violently reject contact. They live in North Sentinel Island, a small and remote island which lies to the west of the southern part of South Andaman Island. They are thought to number 40 to 500 members with a median estimate of 250. Helicopter surveys after the 2004 Indian Ocean tsunami indicate the Sentinelese survived, at least initially.
It is estimated that they have lived on their island for 60,000 years. Their language is markedly different even from other languages on the Andamans, which suggests that they have remained uncontacted for thousands of years. They are thus considered the most isolated people in the world, and they are likely to remain so.
