My proposal would be a new tax - like property tax.
All advertising - broadcast or printed, movie product placements, distributed flyers, mailings, etc. would be subject to this tax.
Hey, if it makes a difference in the life of one child it will all be worth it.
But most of the states that charge sales taxes already have you covered for the others.
As for income tax, the states are far ahead of you. All income is portioned by state for media companies. So for example, if 10% of a paper's subscriptions are in Virginia, that state gets 10% of the paper's revenue/expenses and pays income tax in that manner....same with broadcast companies. Kansas has 3% of a company's viewership, Kansas gets 3% of the company's revenue/expenses for purposes of state income tax. Trust me, nothing goes untaxed. You have nothing to worry about.
