Microsoft, Google and AOL are getting ready to meet with New York assembly­man Richard Brodsky, a Demo­crat from Westchester County, to discuss a privacy bill that he is developing, which could have strong implications for the online advertising industry. "The bill is very broad and it would make a lot of legitimate practices illegal. [It] would basi­cally make ad networks illegal," said Mike Zaneis, VP of public policy at the Internet Advertis­ing Bureau (IAB).
