railway network in the second half of the nineteenth century meant most in the North lived within reach of the coast, and seaside towns saw a major tourism boom. By around 1870 Blackpool on the Lancashire coast had become overwhelmingly the most popular destination – not just for Northern families, but many from the Midlands and Scotland as well. Other resorts popular with Northerners included Morecambe in northern Lancashire, Whitley Bay near Newcastle, Whitby in North Yorkshire, and New Brighton on the Wirral Peninsula, as well as Rhyl over the border in North Wales. The same social forces that had built these resorts in the nineteenth century proved to be their undoing in the twentieth. Transport links continued to improve and it became possible to travel overseas quickly and affordably. The Belgian coast at Ostend became popular with Northern working-class tourists in the first half of the twentieth century, and the introduction of package holidays in the 1970s was the death of most Northern seaside resorts. Blackpool has maintained a focus on tourism, and remains one of the most visited towns in England, but visitor numbers are far below their peak and the town's economy has suffered – both employment rates and average earnings remain below the regional average. The wild landscapes of the North are a major draw for tourists, and many urban areas are looking for regeneration through industrial, heritage and cultural tourism: of the 24 national museums and galleries in England outside London, 14 are located in the North. In 2015, Northern England received around a quarter of all domestic tourism within the UK, with 28.7 million visitors in 2015, but only 8% of international tourists to the United Kingdom visit the region. Media Television As part of a drive to reduce media centralisation in London, the BBC and ITV have moved much of their programme production to MediaCityUK in Salford and Channel 4 has moved its headquarters to Leeds. Of the four national evening soap operas, three are set and filmed in Northern England (Coronation Street in Manchester, Emmerdale in the Yorkshire Dales and Hollyoaks in Liverpool but set in Chester) and these are important to the local TV industry – the commitment to Emmerdale saved ITV Yorkshire's Leeds Studios from closure. The region also has a reputation for drama serials and has produced some the most successful and acclaimed series of recent decades, including Boys
