Do you know what, this actually annoyed me about my Panasonic TV, it does exactly the same.

When I go into the "Internet" function, it shows me ads at the bottom. Why am I seeing these ads?

For example, in the UK we pay the TV license to BBC to NOT see ads. We are paying for a TV so why am I still seeing ads?

If I was renting a TV at a reduced cost or some type of freemium model then I would expect it, takes the biscuit a little I say.
