Bresnan, CableOne, Knology and WideOpenWest are all backing off their associations with NebuAd, a company that tracks the actions of consumers on the Web with the aim of mining that data for marketing information that could be of interest to advertisers.

The Associated Press reports that all of those companies have recently ended or curtailed trials with NebuAd over concerns about possible privacy violations.

And it’s not just MSOs – Embarq and CenturyTel have also recently been compelled to distance themselves from NebuAd.

NebuAd has insisted all along that it protects consumers’ privacy, but after months of trying, the company has not been able to convince consumers’ rights groups, nor quell the concerns of Congress, which began to scrutinize the company during the recent flare-up of the network neutrality debates.

Charter Communications and CenturyTel were among the first companies to suspend their activities with NebuAd. Both did so in June, after consumers raised concerns about privacy violations associated with NebuAd’s methods.
