Re: Engineering change at the BBC?
"The BBC doesn't "do" engineering "
CEEFAX, PAL Colour TV, 625 line transmissions, The BBC 'B', Satellite Broadcasting, Digital Services, the iPlayer, micro:bit, Smart TV services.
There's also the work that the BBC did in improving loudspeakers including the BBC LS range. That work is one reason that British loudspeakers are still considered among the world's best designs.
By all means kick the BBC, but keep it factual.
