The jingle market was great until $500.00 portastudio's came on the market. Then, clients who used to pay $3,500.00 and up (the 70's and 80's)were being hustled by youngsters offering a package of a .30, .60 and .10, usually with a music and vocal intro and out, for flexibility.
That market has been replaced by YouTube video for corporate clients. Strong audio is the reason I'm booked up all the time at top dollar.
Don't know how I'd do if I were only selling music and not the package.
Right now, opportunities presented by popularity of YouTube projects for sound scores is better than ever. Of course, you have to be able to stay up thirty hours straight, and play under extreme pressure from producers, placement deadlines, clients, etc.
Wish this market had been around 20 years ago.
