I'm not talking "early losses". Microsoft lost $1 billion every year on Bing until at least two years ago. Compare that to Google profiting billions every year and you can see Bing is no Google.
Like you, I had similar information and I've tried a couple of different paths to figure out what the current state of affairs is. There are some Microsofties reading this, feel free to let me know off line (I'll keep your confidence) whether or not these gains are being translated into bottom line improvements yet.
Since Bing is only 5 years old, I would consider losses 2 years ago to still be early. Also, reported numbers were usually on Microsoft Online Services Division as a whole which included other money losing businesses like MSN
