"I think that we are not, I would say... happy with the ability to find and discover content as easily as we'd like for consumers to be able to do that," Greenberg told MTV Multiplayer.

Greenberg said that Xbox Live's interface was never intended to serve the amount of content that the platform currently offers. The steady stream of new downloadable items such as games, new content and videos recently prompted Microsoft to consider delisting underperforming Xbox Live Arcade titles.

"I think a lot of that is we built Xbox Live Marketplace for a few hundred items and now we have 17,000 items," Greenberg added. "We built a small store and we filled it with lots of lots of stuff. We're feeling some of these growing pains and [the new policy] is one of those tradeoffs we've had to make."

Greenberg went on to suggest that the last major update to the Xbox Live Marketplace's interface, which arrived as part of an Xbox 360 dashboard update last fall, wasn't enough to solve the problem. Though the manager would not specify whether or not a complete overhaul is in the cards, he noted that some upcoming changes should ease the bloat.

"Longer term, we're looking to make the ability to find content and organize the 17,000 pieces of content we have a lot better."
