Tourist numbers peaked in the first half of the 20th century, prior to the boom in cheap travel to Southern Europe that also saw the decline of tourism in many similar English seaside resorts. The Isle of Man tourism board has recently invested in "Dark Sky Discovery" sites to diversify its tourism industry. It is expected that dark skies will generally be nominated by the public across the UK. However, the Isle of Man tourism board tasked someone from their team to nominate 27 places on the island as a civil task. This cluster of the highest quality "Milky Way" sites is now well promoted within the island. This government push has effectively given the island a headstart in the number of recognised Dark Sky sites. However, this has created a distorted view when compared to the UK where this is not promoted on a national scale. There, Dark Sky sites are expected to be nominated over time by the public across a full range of town, city and countryside locations rather than "en masse" by government departments.
