the Fields, weekly drama, English-language lessons, and comedy including Just A Minute. Other notable previous programmes include Letter from America by Alistair Cooke, which was broadcast for over fifty years; Off the Shelf with its daily reading from a novel, biography or history book; A Jolly Good Show, a music request programme presented by Dave Lee Travis; Waveguide, a radio reception guide; and The Merchant Navy Programme, a show for seafarers presented by Malcolm Billings; The Morning Show, Good Morning Africa and PM, all presented by Pete Myers in the 1960s and 1970s. Since the late 1990s, the station has focused more on news, with bulletins added every half-hour following the outbreak of the Iraq War. News News is at the core of the scheduling. A five-minute bulletin is generally transmitted at 01 past the hour, with a two-minute summary at 30 past the hour. Sometimes these are separate from other programming, or alternatively made integral to the programme (such as with The Newsroom, Newshour or Newsday). During such time slots as weeknights 11pm-12am GMT and that of Sportsworld, no news summaries are broadcast. As part of the BBC's policy for breaking news, the Service is the first to receive a full report for foreign news. Availability Americas BBC World Service is available by subscription to Sirius XM's satellite radio service in the United States. Its Canadian affiliate, Sirius XM Canada, does the same in Canada. More than 300 public radio stations across the US carry World Service news broadcasts —mostly during the overnight and early-morning hours— over AM and FM radio, distributed by American Public Media (APM). Some public radio stations also carry the World Service in its entirely via HD Radio. The BBC and Public Radio International (PRI) co-produce the programme The World with WGBH Radio Boston, and the BBC was previously involved with The Takeaway morning news programme based at WNYC in New York City. BBC World Service programming also airs as part of CBC Radio One's CBC Radio Overnight schedule in Canada. BBC shortwave broadcasts to this region were traditionally enhanced by the Atlantic Relay Station and the Caribbean Relay Company, a station in Antigua run jointly with Deutsche Welle. In addition, an exchange agreement with Radio Canada International gave access to their station in New Brunswick. However, "changing listening habits" led the World Service to end shortwave radio transmission directed to North America and Australasia
