Twitter Ad Revenues Rising … BUT …

eMarketer forecasts that Twitter ad revenues will rise this year and next, from $45 million in 2010 to $150 million in 2011 to $250 million in 2012, BUT the one prevalent question is if Twitter has saturated the marketplace.

Can Twitter maintain the same stratospheric growth it has experienced in the past several years? Has it plateaued? The simplicity of Twitter is its inherent beauty, but it’s the visual, engaging element that has continued to feed Facebook’s growth.

Twitter seems to be growing most in spam-type accounts that people open up and fill with autotweets, program with auto retweets, etc, etc.

Overall ad revenues for the major social networks (MySpace isn’t a major any longer) are trending up. Twitter and Facebook to a lesser extent are in a race to grab as much market share as possible, before the next big thing appears on the scene.
