Blake's 7

Blake's 7 was broadcast in 25 other countries. It had a low budget but featured many tropes of space opera, such as spaceships, robots, galactic empires and aliens. Critical responses have been mixed; some praised the programme for its dystopian themes, strong characterisation, ambiguous morality and pessimistic tone, as well as displaying an "enormous sense of fun", but others have criticised its production values and dialogue, and accused it of lacking originality. It retains a sizeable and enthusiastic fan base, and was described in The Guardian's 40-year retrospective as "a bold show that wasn't afraid to break formulas".

A limited range of Blake's 7 merchandise was issued, and books, magazines and annuals were published. The BBC released music and sound effects from the series, and several companies made Blake's 7 toys and models. Four video compilations were released between 1985 and 1990, and the entire programme was released in videocassette beginning in 1991 and re-released during 1997, and as four DVD boxed sets between 2003 and 2006. The BBC produced two audio dramas during 1998 and 1999, featuring original cast members, that were broadcast by BBC Radio 4. Although proposals for live-action and animated remakes have not been realised, Blake's 7 has been revived with several series of audio dramas from Big Finish featuring the original cast, and an audio drama reboot with new cast from B7 media.

Starting in 2024 the series was released on Blu-ray, one series per year with updated special effects for all episodes.
