“The presidential campaign for Sen. Tim Scott (R-S.C.) is launching an $8 million advertisement buy, marking a second major investment by the campaign since Scott announced his presidential run three months ago.  According to a senior Scott official, the ad buy dedicates $6.6 million toward television ads. Scott will also launch a six-figure radio and digital ad campaign during that period.”

Yup, TV gets the lion's share.  For radio, a smallish percentage as per usual.
