The days of pixelated faces and choppy audio on video calls are behind us. Video conferencing has become the standard way businesses, schools and healthcare providers communicate across distances.
The global video conferencing market was valued at roughly $10 billion in 2025 and is expected to reach $12 billion in 2026, growing at around 12 per cent year on year (Precedence Research). Enterprise spending continues to climb as remote and hybrid work models become permanent.
Video conferencing saves time and money, improves collaboration and makes it possible to work with people anywhere in the world. This guide covers how the technology works, the main types, the benefits and the industries where it is having the biggest impact.

Video conferencing is a real-time communication method that lets individuals or groups connect via audio and video over the internet.
Unlike a phone call, video conferencing lets you see the people you are talking to. That matters more than it sounds. Facial expressions, gestures and body language carry meaning that voice alone cannot. In practice, video conferencing works as a virtual meeting room where you can:
Whether you are running a team meeting, conducting a job interview, attending a virtual lecture or consulting a doctor remotely, video conferencing is the tool that closes the distance.
Video conferencing involves two steps: compressing and transferring.
Your camera and microphone capture video and audio. Codecs compress that data into small digital packets. Those packets travel over the internet, often through a cloud server that routes them to every participant on the call. At the other end, the data is decompressed back into visuals and sound, recreating the conversation in real time.
The result is something that feels close to being in the same room, with three advantages over a traditional phone call:
You do not need expensive equipment to start. The basics are:
For better video quality, an external webcam can make a noticeable difference. See our guide to the best webcams for video conferencing for current recommendations, and our tips on home lighting for video calls for an easy upgrade that costs nothing.
Video conferencing is not one-size-fits-all. Different setups suit different situations:
A direct video connection between two people. This is the simplest form: one-on-one interviews, quick check-ins, video banking or doctor-patient consultations.
Three or more participants join the same call. This is the format most people think of when they hear 'video conferencing': team meetings, online classes, brainstorming sessions and client calls. Features like breakout rooms let hosts split larger groups into smaller discussions.
Dedicated conference rooms with specialised hardware: high-definition cameras, large displays and room-filling microphones. Used for executive meetings, boardroom presentations and situations where professional production quality matters.
Software that runs on a computer or laptop, letting individuals join calls from anywhere with an internet connection. This is the most common setup for remote workers and the format that grew fastest during and after the pandemic.
High-definition visuals and spatial audio designed to create the feeling of being in the same room. Used for high-stakes negotiations, international collaborations and large-scale meetings where physical presence would normally be expected.
Video conferencing is not just a substitute for in-person meetings. For many use cases, it is better. The role of video conferencing in business communication has grown beyond simple calls into a core tool for sales, hiring, training and customer support. Here is why organisations keep investing in it:
Connect from anywhere, at any time. Remote workers, distributed teams and global organisations all depend on video conferencing to stay aligned without requiring everyone to be in the same building.
Travel, accommodation and venue hire add up quickly. Video conferencing removes most of those costs. For businesses with international clients or distributed teams, the savings are significant.
No commute, no airport queues, no waiting for a meeting room. Meetings start on time and scheduling is simpler when nobody needs to travel. The time saved goes back into productive work.
Real-time screen sharing, whiteboards, document co-editing and breakout rooms make video meetings more interactive than a phone call and, in some cases, more efficient than sitting around a physical table. Decisions happen faster when everyone can see the same information.
Fewer flights, fewer car journeys, less energy spent on office space. Video conferencing is one of the simplest ways for organisations to reduce their environmental impact without reducing their output.

The applications go well beyond team meetings. Here is how different industries are using video conferencing:
Sales teams use video calls for product demonstrations, client pitches and account reviews without the cost or time of travelling to each prospect. Marketers run webinars, virtual events and video presentations to reach wider audiences.
For example, HubSpot, a global marketing software company, uses video conferencing extensively for sales demos, lead nurturing and customer support.
HR departments conduct remote interviews, onboard new hires and run team meetings across time zones, increasingly using AI tools for HR and AI in staffing to support these processes.
GitLab, one of the largest fully remote companies, conducts all interviews and internal meetings virtually by default.
Video conferencing platforms are used for virtual training sessions, workshops and educational seminars. Organisations can deliver interactive learning experiences to employees or students anywhere in the world, making continuous development possible without travel.
Coursera uses video conferencing to connect instructors with students globally, adding live sessions to its on-demand course library. For educators building their own virtual classrooms, Digital Samba offers a guide to virtual classroom equipment and the benefits of virtual classroom training.
Video conferencing has become a core part of healthcare delivery. Remote consultations, diagnostic assessments, patient monitoring and virtual therapy sessions are now standard in many healthcare systems. Telehealth platforms provide secure, confidential communication between providers and patients, improving access for people in remote areas or with mobility limitations.
Amwell, a major telehealth provider, offers virtual consultations for a wide range of conditions. For healthcare organisations building their own solutions, Digital Samba's telehealth video API provides GDPR-compliant, end-to-end encrypted video that can be embedded directly into patient portals.
Video conferencing technology continues to evolve. The biggest shifts in 2026 include AI-powered meeting assistants that automate follow-ups and action items, stronger security measures including deepfake detection for video feeds and growing demand for embeddable video APIs that let businesses build conferencing into their own products.

The technology behind your video calls matters. The platform you choose determines video quality, security, reliability and how well the experience integrates with your existing tools.
Digital Samba Embedded is a video conferencing API and SDK designed for businesses that want to build video into their own products. It offers:
Whether you are building a telehealth platform, an e-learning solution or a customer-facing product that needs video, Digital Samba gives you the building blocks.
