Phonographic

I often wonder why Mandarin and Cantonese writing did not incorporate phonograms amongst the logograms. I am thinking of Bopomofo and other phonographic inventions. I know that in other Chinese topolects as Hokkien, mixed phonographic-logographic text has been tried, in different versions. Japanese is just this way.

According to the International Federation of the Phonographic Industry, worldwide recording industry revenue rose by 3.2 percent in 2015 to $15 billion, due mostly to an increase in streaming subscription sales, which overtook physical sales for the first time.
