More often than you'd expect (Score 1)

I work for a marketing company - primarily in email, but the company handles everything. My area is databases, data warehousing and reporting. For our code, we have twice a week change management meetings if there are any changes to be discussed. Given that timeframe, officially we go to production as often as twice a week. In practice, we occasionally fudge a meeting and will get caught up after the code has been promoted to ensure that i's are dotted and t's crossed.
