Not quite as fun, but I used to have a Sharp LCD TV that would send you "emails" internally letting you know about things. Like "there are new channels to tune" and "here's what you watched the most last week" (which was inevitably HDMI, but it would break down the percentages of each input.)
It wasn't sending them out anywhere, as it had no internet link, this was entirely a simulation, a bit like a video game email system. Every time you turned it on it would go "you have new messages!" if it had generated one. Very cute.
