At first the BBC alternated Baird's mechanical 240 system and Marconi-EMI's 405 electronic system.   It soon became clear that the 405 line system was much better and it has been the basis of all television systems for decades....more lines but essentially the same system.

The 405 line had a clever bit as it wasn't updating lines sequentially, but it was like two pictures intermingled.
