Some good news from The Advertising Council. Despite an extremely competitive ad environment, public service advertising campaigns pulled in an estimated $1.5 billion in donated media time during 2000.

The radio industry topped supporters, donating $708 million. Radio reached the top supporter spot in 1999 as well, with $598 billion in donated time.

According to Ad Council figures, the Internet produced the largest increase in support. Web banners in 2000 registered more than 11 billion impressions worth close to $392 million — that’s an increase of 9 billion impressions and $325 million from 1999.

The top five Ad Council campaigns in 2000 were Reduce. Reuse. Recycle, 4-H, Crime Prevention, United Negro College Fund and Earth Share.
