By the end of the 1960s the BBC television programme Doctor Who had enthralled a generation of children.  The police telephone box and the staccato-voiced Daleks had become household icons; watching the flickering black-and-white images of alien monsters and marvels had become a Saturdat teatime ritual for millions.

In Juanuary 1970 Doctor Who returned for a new season - and burst into living rooms in full colour and with a new, dynamic actor in the leading role.

Jon Pertwee was succeeded as the Doctor by Tom Baker, whose flamboyance during his seven-year tenure ensured that the Doctor would be confirmed as one of TV's most memorable characters.

Meanwhile, advances in technology produced more believable monsters and more spectacular special effects.  More and more scenes were filmed on location.  Doctor Who became more popular than ever, with adults now outnumbering children in the continuously rising audience.

The Sevenities is a definitive record of Doctor Who's second decade.  It is illustrated in full colour throughout the book with an unrivalled collection of historic photographs.

David J Howe, Mark Stammers and Stephen James Walker have spent many years researching and writing about Doctor Who.  Together they have written The Sixties, described by Stage & TV Today as 'one of the best books about television ever,' and the Handbook series of paperbacks about the individual Doctors.  David J Howe created Timeframe, the glorious colour scrapbook celebrating 30 years of Doctor Who, while Mark Stammers and Stephen James Walker have edited the first two Decalog collections of short fiction.
