How would you convince the elderly to go online?

I recently spent a half an hour waiting in the local office of the Social Security Administration, which gave me plenty of time to ponder the process that lead to the creation of these posters.

Thanks to Nick at Nite, I loved watching the Patty Duke show when I was a kid.

The theme song is really catchy though.
