Free software played a significant part in the development of the Internet, the World Wide Web and the infrastructure of dot-com companies.[58][59] Free software allows users to cooperate in enhancing and refining the programs they use; free software is a pure public good rather than a private good. Companies that contribute to free software increase commercial innovation.[60]
The Opera browser has been keeping up with the big boys for years, and it does so now by incorporating features no other browser has, in particular a built-in VPN service to keep your browsing secure, as well as ad blockers, a turbo mode, and even a battery saver that lets your laptop run longer than other browsers accessing the same content. It also comes in multiple versions for mobile, including Opera Mini, which compresses pages before you even load them.
Commenting on Websites: Sites like Huffington Post, Entrepreneur and Forbes all rely on social media sign-ins. This means when you comment on these sites; you are logged into another site and posting as that profile. You can find the hottest articles, read the comments and connect with the commenters on their respective social media profiles. It’s one of the easiest ways to find leads. 
It is also possible to purchase products in small "trial size" containers. This is common with toiletries such as shampoo, which are useful for vacations or other travel, where large bottles or other containers would be impractical (or more recently, not permitted for air travel). These are also often provided in hotel and motel rooms for the guests. Samples may also be loaned to the customer if they are too valuable to be given for free, such as samples of a countertop or of carpet to be used for remodeling. Sometimes companies in b2b market will offer sample of data or service for free before engaging business relationship.
Your local library isn't just a place you go to find a new novel without paying for it. Libraries subscribe to a number of different business directories, which makes them a perfect place to get leads for free —especially for B2B salespeople. These directories aren't limited to resources like Internet reverse lookups, although such a tool can be very useful if you're looking for business leads. Many companies make it their business to organize information about both the company and their consumers. This information is compiled into a huge database, and this database is pure gold for any salesperson looking to create a new lead list.
It's not super popular in the US and not even our favorite messaging app, but you can't ignore the 800-pound messaging gorilla that is WhatsApp—since it was purchased by Facebook for almost $20 billion and it has over a billion users worldwide. It offers end-to-end encryption, has animated GIF support, group chat for up to 256 people, document sharing, voice and video calls, one-tap voice messages, and a Web-based interface you access by scanning a QR code with the app on your mobile device. It recently added macOS and Windows desktop versions. 

The FSF list is not prescriptive: free licenses can exist that the FSF has not heard about, or considered important enough to write about. So it's possible for a license to be free and not in the FSF list. The OSI list only lists licenses that have been submitted, considered and approved. All open-source licenses must meet the Open Source Definition in order to be officially recognized as open source software. Free software on the other hand is a more informal classification that does not rely on official recognition. Nevertheless, software licensed under licenses that do not meet the Free Software Definition cannot rightly be considered free software.
As the name implies, PowToon concentrates on providing a method for animating presentations. The free version is limited to 100MB of online storage and you only get basic image resolution and five minutes per presentation, with limited access to royalty free music and styles. But that should be enough to get you started and a limitation worth working with to make a great presentation.
This could be the most high-end free software ever: it's the very tool used to render the images you see in Pixar's movies. That's because RenderMan was developed by Pixar in-house for that purpose, but became free for non-commercial use. It's not going to do you much good without other software such as Autodesk's Maya for creating 3D models. But budding artists and filmmakers will want to take note. You'll need a 64-bit system to run it.
