Several services of interest to marketers are debuting here at Demo in San Diego.

The MuseStorm Content Engagement Platform is a service that simplifies the creation of widgets, those ubiquitous branded medallions that show up on blogs and social networking sites and deliver video, images and text streams. The founders claim that businesses typically spend $30,000 to create a widget (not an unrealistic figure, from what I’ve seen) and that they can reduce that process to a few minutes.

Drag and drop the content container and the relevant content into a workspace, add logos and messages/instructions and generate the final product without coding. MuseStorm provides components to e-mail a friend, download a brochure, request a follow-up, vote, comment, etc. and delivers final code that can be dropped into any html page. More importantly for marketers, the company has back-end tracking and reporting to tell marketers what’s resonating with the audience and what’s falling flat. Pricing is correlated to traffic.

UK-based Real Time Content Ltd. has one of those “why didn’t I think of that?” services. Adaptive Media Version 1.0 delivers targeted video to visitors based upon interests they specify. It’s a simple concept that must be devilishly difficult to implement.

Consider the range of videos that a car company might want to show a visitor. A 25-year-old single male might want to see the fastest sports car while a 35-year-old mom could prefer a demonstration of safety features. On most websites today, every viewer gets the same video, no matter what their interest.

Real Time Content stores a menu of videos, text messages, images and calls-to-action that can be dynamically assembled and delivered to visitors depending on information they provide. So that 35-year-old mom gets a video and text overlay talking about safety features along with an invitation to request a brochure while the single young male might get an invitation to sign up for a test drive. The company has reporting and analytics to show marketers what’s working.

Shoutlet is a tool for monitoring Web 2.0 campaigns. The service includes a platform for distributing content like video and RSS feeds to dozens of sites, a widget-building function, RSS feed creator and e-mail campaign manager. The reporting is supposed to be where to Shoutlet shines. The developer, Sway, is a marketing services agency specializing in social and viral media. It should know what kind of reports marketers want.

Sway intends to price under $10,000 a month, which would make it cheaper than the influence-tracking services offered by most of its competitors.
