In consumer electronics, the innovation ceiling has been reached in most major product categories.

What’s left to improve in computers?

Digital cameras have seen 98 percent of the innovation they’re going to enjoy.

Flat-panel HDTVs — plasma and LCD — pretty much have advances in Internet connectivity remaining. How much more amazing can the picture get? Not much. And I’m not sure mainstream consumers will be buying 3DTVs. The industry is working hard on making 3DTVs the next major category in televisions — there’s a lot of money to be made if this happens — but manufacturers have yet to convince consumers. Remember, most people that might consider a 3DTV have a relatively new HDTV with an excellent picture in their home already.

MP3 players have reached a peak. Little left to innovate there.

And I would argue that the majority of smart phone innovation is behind us. What’s left to do? The screens are brilliant, on-board memory is huge, you can watch thousands of movies and tv shows on most phones. Hundreds of thousands of apps. Electronic books. They’re amazing. The remaining improvements are incremental.

Tablets will see a lot of innovation in the next few years (at the expense of netbooks, which are finding their very brief limelight to be fading). But that’s the only major consumer electronics category I can think of.

Most product types on the market are pretty close to as good as they’re going to get.

So how can you sell more of them?

Improve your marketing. Improve what you say about your products. Don’t talk technical specifications. Tell consumer stories.

Improve how you talk about your products.

Improve your consumer education.

Your marketing has room for endless innovation. Unlike your products, it is oceans away from any ceiling.

So, innovate.
