Today marks 75 years since the first regular high definition (as in 405 line) television service began broadcasting from the BBC studios at Alexandra Palace in North London.
The BBC’s Nick Higham has posted two videos about the anniversary: BBC celebrates 75 years of TV and Behind the scenes at Alexandra Palace, the cradle of television.
There is also anniversary coverage on:
- The BBC Story site
- The About the BBC Blog
- Ariel
- BBC News: the story of the competing Marconi-EMI and Baird systems in 1936
