Be honest: Can you work all the buttons on your TV remote? If your household is anything like ours, you may well have four or five of them to master.
A company called Fobis Technologies has distilled the functions to their simplest forms with their line of "Weemotes" aimed at children (not to be confused with the homonymous "Wiimote.") But we frankly think the concept--and perhaps these products--could well find a market among addled adult viewers like us as well.
The Weemote can be programmed for up to 10 channels, as Chip Chicklets notes, so it could be a convenient alternative to parental blocking systems that we'll probably never figure out anyway. The kids will like the bright colors and button shapes too.
