This year marks the first year that ads have been permitted on Davis School District buses. Ads are now placed on 95 of 211 buses, according to Chris Williams, community relations director. The placement has brought in $20,316 to the district. The money generated goes to transportation, which frees up money for other school needs. Alpha Media has the district contract for the ads and besides coordinating sales, applies the ads to buses. The district gets about 63 percent of the revenue generated.
