CNN's coverage of World Autism Day Wednesday paid off for CNN.com and iReport.com. CNN.com received more than 6 million page views of the content related to the medical team's autism coverage. iReport.com, meanwhile, received nearly 450 contributions from people who shared personal stories about living with autism. This is the first major health initiative on the new iReport.com which launched in February.

Insiders tell TVNewser, previous day-long coverage for events, including World Aids Day and World Refugee Day, scored well but nothing to the extent Autism Day did.

As for the cable contribution, viewers were not as tuned in to the coverage. CNN averaged 122K A25-54 viewers during the day and 196K in prime time. That's the lowest demo viewership for CNN in total day, this year. By comparison on Wednesday, FNC had 230K total day and 396K demo viewers in the prime time; MSNBC had 156K total day and 315K in prime.
