CBS said today it has acquired online television guide Clicker.com and named co-founder and CEO Jim Lanzone President of CBS Interactive. Terms of the deal were not disclosed.

In his new role, Lanzone will manage all of CBS Interactive’s operations globally. He replaces Neil Ashe, who was President of CBS Interactive since 2008 and announced in December he would leave the company when a successor was named.

Before Clicker, Lanzone was the CEO of Ask.com where he held a number of executive roles ranging from SVP of Product Management, to General Manager of Ask Jeeves U.S., and finally CEO. After leaving Ask, Lanzone joined Redpoint Ventures as an Entrepreneur-in-Residence, and raised $8 million to develop Clicker in October 2008.

“As we look to the future, CBS has the kind of platform that can take Clicker to the next level as we look to create a lasting, meaningful brand and destination.  We couldn’t be happier to become part of their family now,” Lanzone said on the Clicker blog.

“What should our users do in light of this news?  Act natural!  Seriously.  Keep sending us your comments and ideas, and we’ll keep building Clicker into the product you need it to be.”
