TBH, having just watched the game at work at LHR most here don't care. Worse, some men fear the ladies doing better then the men (potentially winning both the WC and Euros within 2 years)!
That's the general vibe (not caring) i've been getting from all my mates back in the UK. No one cares which is a massive shame. Even my non footballing wife agrees how refreshing it is to see the women not dive around like the men.
My (probably baseless) hunch is that countries where there is large unfulfilled market for football in general - due to men's sports crowding the market - will be those where women's game can prosper and be watched by men an women. USA is a case in point.
Another view could be that development of women's football depends on having strong women's league which often means existing clubs putting money into creating women's teams with all the support and framework required. That would be the case of England? Their women's league is strong.
Spanish clubs seem to be also doing well for women's teams. This would then be the reason we are seeing Spain in ascendance while traditionally strong teams of the past (Germany, Norway) perhaps not as prosperous now, with smaller leagues?
Looking forward to others' comments.
