MSNBC.com ‘roadblocks’ interactives with ads

MSNBC.com has started adding a type of “pre-roll” ad before some of its interactive features. We first noticed this Monday on the network’s citizen journalism photo gallery, where an ad for American Airlines appeared before the content loaded.

Similar to pre-roll video ads, the advertisement “takes over” the page, with the user blocked from clicking or using the content until after a set period of time has passed.
