The transition from window shopping to e-shopping powered by the Internet has significantly transformed the retail landscape in the following ways:

**1. Enhanced Accessibility and Convenience:**

With online shopping, consumers can browse and buy products 24/7 from the comfort of their own homes, without geographic restrictions. 

**2. Price Comparison:**

The Internet has made it easier for customers to compare prices across different retailers instantly, fostering more competitive prices and informed purchasing decisions. 

**3. Wider Variety:**

E-commerce platforms offer an endless aisle of products, giving customers a much wider variety to choose from compared to traditional brick-and-mortar stores.

**4. Personalized Shopping Experience:**

Online retailers use data analysis to understand individual customer behaviour and preferences, and can tailor the shopping experience accordingly by offering personalized recommendations and offers.

**5. Social Shopping:**

Online shopping often integrates with social media, allowing consumers to share opinions and reviews, creating a social shopping experience. 

**6. Cost Efficiency:**

For businesses, e-commerce lowers costs as it eliminates the need for physical retail space and the associated overhead costs.

**7. Omni-channel Retailing:**

The Internet also allows for a seamless integration of online and offline shopping experiences (click-and-collect services, online reservations for in-store pickup etc.).

**8. Delivery and Returns:**

Online retailers introduced home deliveries and easy return policies, making online shopping a hassle-free experience for customers. 

However, the shift to e-commerce also presents challenges. Retailers need to tackle issues such as tech infrastructure, cyber security, logistics management, and maintaining customer trust in an online environment. Furthermore, despite the growth of online shopping, physical stores still offer unique value, such as tactile product experiences and personal customer service, that online shopping has yet to fully replicate. Hence, a combination of both physical and online stores, known as brick-and-click, is seen as an ideal retail model by many.

Certainly. The brick-and-click model, also known as click-and-mortar, is a business strategy that combines both offline (bricks) and online (clicks) presences. Essentially, this means a company has both physical stores and an online platform, allowing customers to shop in the manner most convenient for them. Here's why it's considered an ideal model:

**1. Customer Convenience:**

Consumers can shop however they choose, be it from their home via digital platforms or in-person by visiting a physical retail store. It also allows customers to order online and collect purchases in-store, called click-and-collect, adding another layer of convenience.

**2. Wider Reach:**

It provides companies with the opportunity to reach a broader audience. While physical stores cater to local customers, the online platform extends a business  s reach globally.

**3. Improved Customer Experience:**

The model allows businesses to leverage the strengths of both platforms. Customers can experience products in-store and make purchases later online, or research online before purchasing in-store.

**4. Increased Sales:**

Studies show that the brick-and-click model often leads to increased sales. Consumers might visit a physical store due to an online promotion, or make additional purchases online after having an excellent in-store experience.

**5. Greater Visibility:**

An online presence increases a business's visibility and credibility, while physical stores provide tangible brand experiences. This dual presence helps a business to build stronger customer relationships and brand loyalty.

**6. Efficient Inventory Management:**

Inventory can be managed more efficiently with an integrated system that tracks and replenishes stock across both online and offline channels.

Despite the benefits, maintaining a successful brick-and-click model does have its challenges. It requires seamless operational integration, a consistent brand experience across all channels and above all, meeting customer's expectations of convenience, pricing, and service both online and offline. But when executed effectively, it provides a comprehensive retail solution that offers the best of both worlds.

Absolutely! Numerous companies across sectors have managed to successfully implement a brick-and-click model. Here are a few prominent examples:

**1. Apple:**

Apple operates physical stores worldwide that allow you to try out and purchase devices. They also have an online store where you can order products to be shipped or picked up in-store, access services, and get customer support.

**2. Walmart:**

The retail giant offers online services ranging from shopping to order pick-up and home delivery. Walmart constantly invests in its mobile app and online store, while still emphasizing and retaining its physical presence.

**3. IKEA:**

Known for its large, maze-like physical stores, IKEA has also ventured online, providing customers with an e-commerce platform where they can order their Swedish-designed furniture to be home delivered or picked up in-store.

**4. Nordstrom:**

This upscale department store chain ensures they maintain their dynamic through a comprehensive online store. Their website offers all the products that are available in-store plus web-exclusive items. They've also became known for their flexible return policy and seamless integration between online and offline shopping.

**5. Best Buy:**

Best Buy's online store allows you to shop for their products online, with choices for shipping or in-store pickup. They've turned their physical stores into an advantage by using them as a network of distribution centers to fulfill online orders quickly.

These companies demonstrate that implementing a brick-and-click model can lead to increased sales, customer reach, and customer satisfaction when executed effectively.
