By the late 1990s, the live studio demonstrations were dropped in favour of purely pre-recorded items. The final series, presented by Adam Hart-Davis, Kate Humble and Roger Black, attempted to revert to the original live format of the show, even using a remix of one of the theme tunes used during its more successful years, but ratings continued to fall, and with only three million viewers in the last series the BBC decided to axe the show. At the time they said that they would produce a number of science special editions under the "Tomorrow's World" "brand" from time to time. The "Tomorrow's World Roadshow" appeared in 2004 with Gareth Jones (co-host of CITV's "How 2") and Katie Knapman taking the helm as the last presenters of a show bearing the "Tomorrow's World" name, before a partial return to television in 2007.
