I won't be surprised with YouTube and Facebook ads, since people have ample of time to spend in the internet.
And to add for that, there are lots of new streamers popped out in Facebook Gaming here in PH despite a call from most citizens of financial assistance from the government. To able to start, streamers need decent streaming equips to cope up with the other streamers (PC supplies zone also take the advantage). In the game I played, ROM SEA, lots of shared streams circulated now gathering subs for their Facebook page and Youtube channel.
Don't have an idea about the facemask industries but for tissue or toilet papers, sales become boom until now. I have a known friend who is a manager of a tissue company named "E*CO (not promoting it lol) and they told me that there's a large demand since the lockdown hit the capital.
