According to the Sydney Morning Herald, one video showed an autistic youth being abused and another depicted a crank call to a Down's Syndrome charity.
The executives were not involved with the creation of the videos, but are accused by Milan prosecutors of failing to control the site properly.
The prosecution is being pushed by an advocacy group for Downs Syndrome, Vividown.
Vividown President Edoardo Cenzi admitted that Google had removed the content within 12 hours after it was told about it, but his outfit felt that these sorts of videos should not be circulated without controls.
Four youths from Turin are already helping coppers with their inquiries.
A spokesGoogle said that the outfit is working hard to identify illegal or offensive content but still depended on outraged users to flag material. µ
