Lunch Ann Arbor Marketing, a weekly networking group for the area's public relations and marketing professionals, expects between 75 and 100 people in weekly attendance for its fall 2010 lineup.

That lineup, announced this week, includes Ann Arbor resident and ESPN commentator Mike Tirico, who will address LA2M on Oct. 20. Tirico will discuss his experiences as a member of the media covering the 2010 World Cup in South Africa.

Tirico's talk "is a highlight in an LA2M series that includes leaders in the digital marketing space," LA2M founder Derek Mehraban, CEO of Ann Arbor-based Ingenex Digital Marketing, said in an e-mail.

"Internet marketing strategy is crucial to marketers and business owners," he said in a press release. "The demand for digital is growing exponentially, and this fall LA2M will challenge Ann Arbor to think digitally and utilize the online space to connect with customers."

The group, which meets Wednesdays from 11:45 a.m. to 1 p.m. at Conor O'Neils on Main Street, is becoming a networking hub for Ann Arbor's marketing sector. The upcoming speakers include professionals who will address Google AdWords, search engine optimization, digital PR and Web site design, Mehraban said.
