Broadcasting has been very important in recording significant Welsh milestones of the 20th century. Here are clips that mark the influence of some of the most important events over the last century, from flooding the Tryweryn valley and other valleys throughout Wales to build reservoirs in the 1960s, to the Miners' Strike crisis of the 1980s, to devolution in the 1990s, and much more.
Please note there are English subtitles available for the Welsh language clips.
