TV color crystal frequncy. Any time one needs to create color display
through a TV set, they'd use one of these.
These are also the cheapest crystal out there since they are
used in most every color TV.
I see these a lot where a 4MHz would work but the controller was
built with cost in mind and 3.6MHz was fast enough.

That's the crystal frequency used in Atari's Pong:
