I use K9 to keep my kids out of offensive web sites especially adult and bad reputation sites. I also like the new "Advanced YouTube Filtering" which seems to be working okay. Now my 11yo daughter can use youtube, which I previously had it blocked. If your kids are old enough talk to them, tell them internet is like a car, it's a great tool, you can use it to go to good places and bad places, so it must be used with responsibility.


K9, retroactively "K9 Mark I" (Leeson), initially appeared in The Invisible Enemy (1977) as the creation of Professor Marius (Frederick Jaeger) in the year 5000. K9 subsequently travelled with the Fourth Doctor (Tom Baker) and Leela (Louise Jameson) as a companion of the Doctor in his adventures in time and space until The Invasion of Time (1978). In this serial, K9 decides to remain on the Doctor's home planet of Gallifrey with Leela. Immediately afterwards, Doctor Who would introduce a second incarnation of K9, played by the same prop; the last scene of The Invasion of Time shows the Doctor unpacking a box labeled "K9 Mk II".
