What is a great product that was poorly marketed?

Google Glass is a prime example of a product with brilliant technology but flawed marketing. Its failure stemmed from several key issues:

• Undefined Target Audience: Google failed to identify a clear, compelling use case for a specific user segment. It was marketed broadly, leaving potential customers unsure of its practical value.
• Misaligned Positioning: It was presented as a lifestyle accessory, yet its functionality didn't offer a significant advantage over existing devices like smartphones, failing to justify its existence.
• Prohibitive Pricing: The $1500 'Explorer Edition' priced it out of reach for early adopters and mainstream consumers, positioning it as an expensive prototype rather than a viable product.
• Privacy Concerns: The always-on camera sparked significant privacy backlash, creating a negative public perception that overshadowed its technological merits.
