Read this: On 5 July 2004, the BBC celebrated the fiftieth anniversary of its television news bulletins (although it had produced the Television Newsreel for several years before 1954). This event was marked by the release of a DVD, which showed highlights of the BBC's television coverage of significant events over the half-century, as well as changes in the format of the BBC television news; from the newsreel format of the first BBC Television News bulletins, to the 24-hour, worldwide news coverage available in 2004. A special edition of Radio Times was also produced, as well as a special section of the BBC News Online website. In 2005 the pioneering BBC television series Little Angels won a BAFTA award. Little Angels was the first reality parenting show and its most famous episode saw Welsh actress Jynine James try to cope with the tantrums of her six-year-old son.
