partially true, Greenland is marketing but Iceland isn't reverse marketing.

The early Norse settlers named the island Greenland. In the Icelandic sagas, the Norwegian Erik the Red was exiled from Iceland with his father, Thorvald, who had committed manslaughter. With his extended family and his thralls (slaves or serfs), he set out in ships to explore an icy land known to lie to the northwest. After finding a habitable area and settling there, he named it Grœnland (translated as "Greenland"), supposedly in the hope that the pleasant name would attract settlers.[27][28][29] The Saga of Erik the Red states: "In the summer, Erik left to settle in the country he had found, which he called Greenland, as he said people would be attracted there if it had a favourable name." [30]

The island's present name came from Flóki Vilgerðarson, who was the first Norseman to intentionally travel to Iceland. According to the Sagas of Icelanders, Flóki coined the name after he climbed a mountain, despondent after a harsh winter in present-day Vatnsfjörður, and saw an ice cap.[26] The notion that Iceland's settlers chose that name to discourage competing settlement is most likely a myth.[26]
