The real break in equipment of electronic television was made by the pupil B. Rozinga V. K. Zvorykin (who emigrated after revolution to America and working at RCA) — in 1923 he submitted the application for the television founded completely on the electronic principle, and in 1931 created the first-ever transferring electronic tube with the mosaic photocathode called "iconoscope" which laid the foundation to development of electronic television.

Объяснение: some - с утвердительными предложениями, означает "немного". Any - с отрицательными и вопросительными, означает каких-либо, сколько-нибудь (предметов). How many и how much - начало вопросительных предложений, означают "сколько", но how many используется с исчисляемыми существительными, у которых есть и единственное, и множественное число (friends - друзья, apples - яблоки), а how much - с неисчисляемыми (sugar - сахар, только единственное число).
