Sponsors pay for what they get. AT&T don’t pay to have their logo on the sidepod, they pay to have their name in the title.
They all pay for a spot on the car. Remember when Renault launched in 2010? They had lots of blank spaces, they could have covered those over with their existing sponsors but they didn’t because that would scare sponsors away.
They’d think “Someone already has that spot, there’s no point investing”
If you keep the space open, sponsors will come and look… we could have our logo there.
