Microsoft, Google, Facebook, among others.

They're popular websites that many people use, but are they invading your privacy with "adware?"

Right now, a Senate committee is looking into such privacy concerns. The 23 member committee includes Republican John Thune from South Dakota and Democrat Amy Klobuchar of Minnesota. They spent Wednesday grilling internet executives about adware, which track customers' internet use and then uses that information to deliver ads, which feature the presumed interests of the customers.

Elissa Weathery of Sioux Falls is one of many people who uses her computer all the time. Companies that track her internet activity make her feel uncomfortable. She said, "I don't know who they're selling it to, why they're selling, what information they're selling."

That's why the Senate Commerce Committee is looking into the matter. They're also looking at how social networking site Facebook monitors your online purchases and then sends messages about the purchases to your friends.

After the hearing, Sen. Thune sent a written statement to KSFY. He said, “The internet has become a powerful economic engine here in the U.S. and around the world. It allows consumers greater choice and access than ever before. As this new market place evolves, it is critical that consumers have knowledge of how their online activity is being used and tracked. Consumers should have every opportunity to learn more about the uses of their personal information. I will continue to use my position on the Senate Commerce Committee to closely watch this issue to ensure that consumer information is adequately protected."

Depending upon what the committee decides, it's possible that new bills could seek to regulate internet advertising. Government agencies, like the Federal Communications Commission would ensure internet users' privacy are not violated.

As for Elissa Weatherly, she just wants the option to avoid targeted ads. She said, "If I want them to target me then it should be my own decision."
