Released on:  May 3, 2022

Version: Lectora 21.2 (12364)

This update includes exciting news as eLearning Brothers is now ELB Learning!   This update is a rebranding to the new company name ELB Learning and an exciting new logo for ELB Learning.  There are no new features included in this release.   Below is the announcement from our CEO, Andrew Scivally.

I'm excited to share that eLearning Brothers is now ELB Learning!

For more than a decade, eLearning Brothers has helped learning professionals create better learning experiences. That mission—and the products and services you know and love—won’t change. 

However, as we’ve grown as a company and watched the learning industry grow and innovate, we knew it was time to step into the future with a new name.

Over the past two years, we’ve acquired six companies, becoming the most diversified learning technology and services provider in the industry. 

We now offer one destination for all of your learning needs, along with more ways to save time and money while experiencing a more seamless learning development process.

We appreciate everyone who’s been with us since we first started rocking the eLearning world as eLearning Brothers. That energy and passion will never go away, but ELB Learning better embodies the direction we see our company, and the learning industry, going in the future.

The new name will not change the support or products you’re currently enjoying from us. Your favorite account reps are still here for you, our product team remains ready to answer your questions and listen to feedback on new features, and you’ll still see familiar faces at conferences and on webinars. 

We’re excited to continue to grow as ELB Learning and offer more ways to help you create better learning experiences. If you have any questions about our new brand, don’t hesitate to reach out.

Andrew Scivally

CEO, ELB Learning
