recently i read an article on digg where it was listed that the list of companies microsoft has aquired over a period of time but i felt another notable site should also find a mention on the list that has 87 domains as of today listed under one ip.
no wonder that company is google, you can view the list here. i am still digging for the sites yahoo has now.
though google has not gone on a spree to but out companies, here are few of the companies either google or microsoft have bought out for their new onslaught.
sketchup – google
onfolio – microsoft
isolatr – yahoo (they took off the bottom line that its a yahoo company the next day i read the article and say bode instead , but i still feel yahoo has bought it out)
you can read the original google domains list article at my friends site .
