Talking Points Memo, the eight-year-old political blog, has hired its first vice president of sales, who will lead its in-house advertising efforts. Diane Rinaldo, formerly director of political advertising at Yahoo!, holds the new position. Until her hire, TPM relied solely on advertising services like Blogads. In March and April, Rinaldo reports, TPM sold more advertisments than it did for all of 2008 (this refers only to in-house sales, rather than total advertising revenue).
