Question: Did Google Alerts Get Sold and Change Their Name?
I got an email about my Google Alerts. It said they were changing their name and owned by some company that isn't Google. What is going on?
Answer: What most likely happened is that instead of setting up a Google Alert, you set a Giga Alert. Giga Alert is not affiliated with Google, but they own the domain www.googlealert.com, and until recently they called their service "Google Alert."
Giga Alert is a fee-based subscription service, while Google Alerts are free.
