Friday is the biggest weekday for radio listening, at least according to one month of PPM numbers from Houston. PPM shows the lift in Friday listening starts at 3pm and peaks in the 10pm to 11pm hour.
Friday had the largest average quarter hour audience in the latest monthlies and Monday is the lowest and each day's audience grows sequentially according to Arbitron data.
How could you take that big Friday afternoon and evening blip in "real" listening (is it that your listeners are wondering what to do this weekend?) and make the most of it, while also using it to build weekend and Monday morning audience shares?
