ICv2 has been keeping tabs on manga sales starting in 2002, and it just put out a new article that print manga sales in America broke records in 2020 and continue to do well in 2021.
The article noted that manga sales had previously peaked in 2007, then dropped between 2008 and 2012. Multiple factors were involved in this drop, including the global financial crisis, Borders shutting down and anime becoming more scarce on TV.
Since then the manga market in North America has been creeping back up, and lately it has been explosive. People reading more during COVID and the accessibility of anime through streaming are two major players. Even as people are coming out of quarantine, the amount of anime available will probably keep manga sales going strong.
