Sony Profit / Spending Help

[sega4life]

Ok, I'm not to good on the currency exchange part of the world...

How much is what, when it comes to Yen/Pound/Dollar currently?

because I'm a little confused on what Sony is doing right now..

From this thread, Sony has a profit of 400mill Yen that's roughly $4.4 - $4.5 million.. (yes/no?)

and...

From this thread, Sony is putting £2 for advertising, Thats almost $2.5 - $3 million.  (yes/no?)

So they make roughly 4.5 million in profit... and spend allot of it on advertising?

See that doesn't make sense.. So I would like help with the numbers because I'm confused.
