Talk about a captive audience.Syndicated columnist, Derrick Z. Jackson, spends some seven hundred words of his latest column bashing a start-up out of Massachusetts that wants to put commerical radio on public school buses. The company, appropriately named BusRadio, would pay school districts in exchange for allowing BusRadio to broadcast ads and bus safety info on the school buses.I agree with Jackson 100%. This idea is shameful. Although I can’t believe that narcotizing is a word, despite what Merriam-Webster tells me.
