The latest is WPIX New York, which the FCC says has to pay a $15,000 fine for violating its limits on TV advertising in kids shows eight times.
The Pokemon character appeared in a commercial that ran during the Pokemon show. The FCC says that turns the whole show into an ad. Which isn't illegal, per se, but it does mean that the station went over the limit on time.
Or, they could just stop hassling the kids. The government doesn't so much want to protect the children, it just wants to meddle. If a kid is too poor to eat and can't read, that doesn't matter. Just don't let them watch tv we don't approve of!
