Lockdown has been, to put it kindly, a mixed blessing. However, one of the bright spots is that talks previously only available to those who could listen in person are now available to all. The Greenwich Industrial History Society is one of the organisations to have made the move online, launching a YouTube channel for their fantastic lectures. So far, these include a fascinating exploration of global telecoms in Greenwich, Charlton and Woolwich by Alan Burkitt-Gray; a lecture from notable local historian Mary Mills; Greenwich's contribution to the first telegraph line linking Britain to India; and underground Greenwich.
Another fantastic YouTube channel is London Historians. This fantastic society has been sharing its annual lectures for some years, but now has monthly lectures and shorter presentations too. Definitely worth exploring!
